After a NoClassDefError classes are still not found even if they have been
installed in the meantime with Java 6
----------------------------------------------------------------------------------------------------------------
Key: SLING-1435
URL: https://issues.apache.org/jira/browse/SLING-1435
Project: Sling
Issue Type: Bug
Components: Scripting
Affects Versions: Scripting JSP 2.0.8
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: Scripting JSP 2.0.10
Scenario - note that this works fine with Java 5, but on Java 6 we have:
- A jsp instanties a class from bundle A with the new operator
- JSP is loaded - everything is working fine
- Bundle A is uninstalled
- JSP invocation results in NoClassDefFoundError (which is expected)
- Bundle A is installed
- JSP is invoked and as soon as the new operator is called a
NoClassDefFoundError is called
It seems that Java 6 behaves differently than Java 5: The jsp can be loaded and
executed, but as soon as the class from Bundle A is used, Java 6 memorieses
that the class was gone inbetween and it is not possible to update this state
somehow. All involved classloaders are not queried anymore
