Vlad & list,
Thanks again for all your insightful suggestions.
I created the test you suggested, and have included my output below.
Unfortunately, crimson.jar is not listed there. Perhaps the classpath the
loader is using and the java.class.path variable are different? Is this
possible?
Could someone out there who has experience with the junit task please
respond to this thread? If the classpath isn't being set properly, there is
likely a serious defect in the task that would prevent many developers from
using it. If at all possible, this defect should be tracked down and
removed, or at least a workaround should be found.

Subject: RE: forked JVM's classpath not clean when using JUnit task
Ok, sorry about not being able to help you more right now but I can't take
any more time away from work at this point. I've looked into junit task
code [I only have ANT 1.4] and that seems to eventually fork a JVM
correctly. Unless someone else sorts this out in the meantime, I leave you
with these clues for now:
- during the fork the JUnitTest class exports all ANT project properties
into a temp props file that is
later picked up by the JUnitTestRunner class in a forked JVM. The idea is to
resurrect the Java runtime as
closely as possible. Well, one of the properties exported is of course
"java.class.path" and it will look something like this from ANT source JVM
[note crimson.jar]:
java.class.path:
D:\J\JDK1.3\lib\tools.jar;D:\ANT\lib\jaxp.jar;D:\ANT\lib\jakarta-ant-1.4-opt
ional.jar;D:\ANT\lib\crimson.jar;D:\ANT\lib\ant.jar;
JUnitTestRunner will later absorb these into the forked JVM. Next, normally
just setting
java.class.path post-bootstrap [like in main() or later] will not have an
effect on the normal app classloader, but [!] I happened to know that
JUnit made use of its own custom classloader. I happened to have v3.7
sources in the office and I looked at the classloader impl: lo and behold,
the first thing it does is set its classpath from "java.class.path"
property.
Anyway, I am not convinced that when JUnit is executed from <junit> task
the same init sequence takes place as when running JUnit standalone but
this is my strongest clue so far. If this proves to be correct, try
disabling JUnit classloader [I remember it has a property for that].
- if the above is a wrong clue, you could get some more data by adding a
quick pseudo-TestCase to you suite and have it output the following:
System.out.println ("app classpath = " + System.getProperty
("java.class.path"));
System.out.println ("current loader = " + getClass().getClassLoader());
Hope this helps,
Vlad.

I have indicated that I want it to be forked, and the build output seems
to
indicate this. I can't know however, wether or not it actually does run
on
a forked JVM. I've included the relevant build file snippet (below) in
case
it helps in your diagnosis.
In browsing the bug-tracking system for junit-related cases, I've noticed
that the junit task has produced buggy behavior in the past, so it's
possible that the junit task is responsible for this error (rather than
the
more commonly used ant code). Are there any people on this list who are
familiar with the junit task specifically? If so, I'd love to hear from
them about this.
Thanks again for your help with this issue.

Is the JVM really forked as you made me think? Otherwise all ANT classes
have access to crimson classes because it is seen by AntClassLoader....

Vlad,

not the case here

all of these things do not contain the crimson class files.
Any other ideas?

I am not familiar with junit task but I can make these comments:
- if crimson is in your JRE ext directory, removing it from the task's
classpath won't make a difference.
- are you sure you are not including the crimson classes through one of
the other jars? How about the CLASSPATH env var?

Subject: forked JVM's classpath not clean when using JUnit task
Hi.
I am aware that the answer to this may already be in the archives. They
are not available at the moment, however, so I thought I'd ask all of you
for your help. If there is a mirror to the mail archive, or another
resource that covers this issue, I'd be happy to read it.
Problem (w2k., ant 1.4.1):
When building a project that includes a junit task, it is apparent that
crimson.jar is accessible from the JUnitTestRunner. This is undesireable,
as my test should have no knowledge / access to crimson.jar. I see this
behavior even when the fork attribute to my junit task is set to true.
As the output (below) shows, the execution of java.exe has the classpath
arg set to a path that does not include crimson.jar. According to the
docs
for java.exe, this path should override any classpath set in the System's
environment variables. Nonetheless, the output from my test clearly
indicates that crimson.jar is available to the test runner (and test).
Is there a way to fix this so that I can cleanly (w/o crimson.jar on the
classpath) run my tests?
