 rawClassName = rawClassName.substring(20);
 String className = convertSlash2Dot(
 rawClassName.substring(0, rawClassName.indexOf('.'))
 );
 classesToTest.add(className);
 }
 }
 
 The NullPointerException occurs on this line:
 
 rawClassName = rawClassName.substring(20);
 
 Because rawClassName is null.
 
 This happens with cacao and jamvm, but not with kaffe, so seems a Classpath 
 problem.

Andrew John Hughes informed that this bug was forwarded to

Bug#351551: cacao: reader.readLine() returns null while reader.ready() returns true

Version: 0.94-1
Severity: normal


Not sure wether this is a true bug, or just incompatibility with Sun JVM 1.5.0 
and kaffe:

When I run a CDK based test suite [1], the OpenSource JVM Test Suite, I get a
NullPointerException, because of this situation:

- reader.ready() returns true
- a subsequent reader.readLine() returns null

The code I deduce this from is:

protected void loadClassList(String classList) throws Exception {
classesToTest = new Vector();
 
// get the src/core.javafiles file
BufferedReader reader = new BufferedReader(new InputStreamReader(
this.getClass().getClassLoader().getResourceAsStream(classList)
));
while (reader.ready()) {
// load them one by one
String rawClassName = reader.readLine();
rawClassName = rawClassName.substring(20);
String className = convertSlash2Dot(
rawClassName.substring(0, rawClassName.indexOf('.'))
);
classesToTest.add(className);
}
}

The NullPointerException occurs on this line:

rawClassName = rawClassName.substring(20);

Because rawClassName is null.

This happens with cacao and jamvm, but not with kaffe, so seems a Classpath 
problem.

This is a classpath problem so it have to be against classpath.
