[JBoss-user] [Javassist user questions] - Re: Modifying CtClass
That's spec. Because the field initialization is done in a static initializer, when you remove a field, you also have to remove the initialization code from the static initializer, which is not a simple task!. So your alternative code (create another ClassPool) is a right solution.

Hi,
anonymous wrote : I'd like to know the differences between "regular" java
accessibility and "via javassist" accessibility.
There should be no difference since Javassist code simply calls
Class#forName() for accessing a class. Does pacote.Anotacao
really exist under a directory included in CLASSPATH?
Another check is to directly call Class#forName("pacote.Anotacao")
in your code. Does the call successfully return a Class object for that class?

Hi, It is a sort of bug of Javassist, but it should not make any real problem since a local variable is not really typed at bytecode level. Your code should run without any problem although a decompielr may claim the type of a local variable remains the same.

For instrumenting a loaded class, you must use HotSwap provided by Sun's JVM. An upcoming new version of Javassist provides a utility class for using HotSwap. So if you are intrested, please down load the CVS HEAD and test it.

[JBoss-user] [Javassist user questions] - Re: Setting a field in a constructor before super is called
I found a simpler way to generate Derived with Javassist.
abstract class Base {
| Base() { System.out.println( getField() ); }
| abstract int getField();
| }
|
| class Derived extends Base {
| int field;
| Derived() {
| field = 1;
| super();
| }
| int getField() { return field; }
| }
|
To generate the Derived class above, first generate the following class:
class Derived extends Base {
| int field;
| Derived() {
| super();
| }
| int getField() { return field; }
| }
|
Then, call insertBefore() on the CtConstructor representing the constructor of
Derived.
The inserted source code is something like this:
field = 1;
Note that insertBefore() inserts the code before super().
insertBeforeBody() inserts the code after super(), though.
I know this post is too late for Howard but it might be useful for others. :-)

Such a tool should be great but the implementation would not be a simple task. First of all, decompiling Java bytecode to appropriate source code is not always possible (well, might be possible but difficult). Even reflecting changes on bytecode to the original source file is not easy since some bytecode manipulation by Javassist is hard to represent in Java.

Your sample code seems weird. At least, the first line:

since makeClass() creates a new empty copy of ClassA.
Can you post a real test program? If the behavior

[JBoss-user] [Javassist user questions] - Re: Setting a field in a constructor before super is called
Thanks. According to my simple study, javac of jdk1.4 and javac of 1.5 seem to compile an inner class in a different way. I found that javac 1.5 initializes a point to the outer class before calling the super constructor. On the other hand, javac 1.4 does not do so. Thus, your sample code of InnerTest throws a NullPointerException if it is compiled by javac 1.4. It might be only a pointer to the outer class that can be initialized before calling a super constructor. I'll study this more.

If you don't need to turn on/off assertions, you can easily insert by
doing this:
insertAfter("if (expr) throw new AssertionError();")
This is equivalent to:
assert expr;
If you want to turn on/off by the -ea option, you have to also insert
the code for checking whether or not the assertion is effective
something like:
if (Foo.class.desiredAssertionStatus())
if (expr)
throw new AssertionError();

[JBoss-user] [Javassist user questions] - Re: NullPointerException occurs when Handler#getType() metho
Thank you for your bug report and pretty good analysis. It is really helpful. anonymous wrote : To avoid this problem, I propose to check null of the return value of | ConstPool#getClassInfo() (type of the exception) in the getType() method Yes, this is a correct and quick fix. However, if your analysis is correct, I think ExprEditor.edit(Handler) should not be called with a finally block. (Note that Javac automatically adds a finally block for each synchronized block. So the exception table includes a catch block or a finally block.) Don't you think I must modify the implementation of ExprEditor rather than getType()? Or, do you like to hook both catch and finally blocks? Let me know your thought. Thx.

[JBoss-user] [Javassist user questions] - Re: inheritance question
It seems that multiple versions of OrgUnitType had been loaded. The error message should be interpreted as that the super class of OrgUnitImpl is a different version of OrgUnitImpl from the version that the cast operator (i.e. the class generated by Javassist) expects. If my observation is true, this is not a problem of Javassist or it cannot be solved with reflection. You should carefully redesign the delegation scheme by class loaders.

$0 means "this". So maybe a right program is:

Note that the arguments are $1 and $2.

This is because the type of $0 is not what you expected.

The real static information of the target object is quite restricted
probably more than you expect. The only information is the static
type of the target object, which is the class declaring the method.
For example,
String s = "foo";
int s = s.concat("bar").length();
In this example, the target expression of length() is s.concat("bar")
and it does not have a name. The only static information is the type
of the target expression is String.

You can obtain the value of a final static field if you go down to the lower-level API of Javassist (I agree that the next release of Javassist support this function with the regular API). You must get a java.bytecode.FieldInfo object from CtField and then obtain a ConstantAttribute object from that FieldInfo. Finally, you must search a constant pool in a class file to find the field value. Note that this way works only for some basic types of fields, for example, int or String.

[JBoss-user] [Javassist user questions] - Re: reading java 5.0 annotations
The current release 3.0 does not provide high-level API.
So you must use the lower-level API, but using it is not difficult.
For example,
| import javassist.*;
| import javassist.bytecode.*;
|
| CtMethod m = ... ;
| MethodInfo minfo = m.getMethodInfo();
| AnnotationsAttribute attr = (AnnotationsAttribute)
| minfo.getAttribute(AnnotationsAttribute.invisibleTag);
| if (atr != null) {
| Annotation an = attr.getAnnotation("Author");
| String s = ((StringMemberValue)a.getMemberValue("name")).getValue();
| System.out.println("@Author(name=" + s + ")");
| }
|
This prints the @Author annotation of the method m.

Although $proceed does not imply this problem, newname($$); would do. I agree this is a bug, which should be fixed soon.

[JBoss-user] [Javassist user questions] - Re: How to value a byte array
Yes, array initialization is quite inefficient in Java. I think your technique using String is a right way.

[JBoss-user] [Javassist user questions] - Re: Limitations
Hi,
1) The limitation is not applied to copied bytecode.
The tutorial says that the compiler does not understand
synchronized. However, the upcoming release 3.0
supports a synchronized statement. So please download
CVS HEAD or wait for several days. We are going to release
3.0 soon.
2) For example,
class A {}
class B extends A {}
class C extends C {}
class X {
void foo(A a) { .. }
void foo(B b) { .. }
}
If the compiled expression is x.foo(new C()), where x is an instance of X, the
compiler may produce a call to foo(A) although the compiler can correctly
compile foo((B)new C()).
This description will be also included in the tutorial coming
with the next release.

If I'm correct, static final fields can be initialized
in a static class initializer, that is,
class C {
static { }
:
}

[JBoss-user] [Javassist user questions] - Re: Field rename
If you don't define a constructor of C at all, your *compiler* define a constructor. It may also modify a constructor you defined so that it will insert some code fragment for field initialization.
