Possible bug in JavaSourceClassLoader?

Hi,

I'm using Janino 2.5.9 to compile generated source code as part of my
JUnit Tests. I have a case where in the source code a statement

If (true)
throw new RuntimeException();

occurred.

The source code compiles fine using JDK 1.6.01. When compiling with
Janino I get a strange StackTrace (see below).
I have no idea what went wrong, so any help is appreciated.

Regards,
Robert

Hi Robert,

can you please develop a minimized test scenario and file a bug report
on jira.codehaus.org? Registration is painless and free.

FYI: If you need a temporary workaround, you can use
"Boolean.TRUE.booleanValue()" (or some other NON-CONSTANT representation
of "true") instead of "true".

CU

Arno
