[jboss-jira] [JBoss JIRA] (JASSIST-228) Powermock / Javassist creates illegal constructors for JDK 1.7.0u65 and 1.8.0u11 with -target 7.

Florian Burka updated JASSIST-228:
----------------------------------

    Description: 
Javassist creates illegal constructors for JDK 1.7.0u65 and 1.8.0u11 with -target 7, I have a test that reproduces it at https://github.com/burka/powermock-javassist-bug .

Somewhere in MainMockTransformer.transform(clazz), I think inside the PowerMockExpressionEditor, the responsible action must have taken place.

If you remove -target 7 it works for both JDK 1.7.0u65 and 1.8.0u11.
