Classloader problem when using cobertura instrumented classes in unit tests
that use Hibernate 3.1
--------------------------------------------------------------------------------------------------
Key: MOJO-194
URL: http://jira.codehaus.org/browse/MOJO-194
Project: Mojo
Type: Bug
Components: sandbox
Environment: Windows XP Prof, SP2
Reporter: Ralf Quebbemann
Classloader problem when using cobertura instrumented classes when running unit
tests using Hibernate 3.1.
Hibernate specifies asm-1.5.3 in its pom which requires the file but cobertura
specifies asm-2.1 in its pom.
The problem seems to be that Hibernate cannot load asm-1.5.3 because cobertura
has already loaded the latest version, which is incompatible.
The problem is described on the Cobertura FAQ page and they recommend:
"Cobertura does not need ASM in your classpath when running tests. If you're
seeing classpath conflicts, just make sure the asm jar that comes with
Cobertura is used only by Cobertura, and only when instrumenting."
Here is the stacktrace:
