ClassFormatError in ASM engine

It is possible for OpenWebBeans to throw a ClassFormatError while constructing an instance of a class that "overrides" a package private method of a super class with an own package private method. Technically, the methods are not overriden, which leads to two methods with the same signature – therefore the FormatError.

de.cewecolor.cdi.blow.sub.SuperClass#setValue(String)
de.cewecolor.cdi.blow.SubClass#setValue(String) extends SuperClass

BeanManager#getReference(SubClass.class) will throw an Error.

Please see the attached example project, it's a very small example triggering the issue (standalone container).

I assume that this problem is related to the switch to ASM. For one, OpenWebBeans 1.1.8 works fine and it can be seen here too: http://issues.gradle.org//browse/GRADLE-2695
Tested also with 1.2.1-SNAPSHOT which uses ASM 4, still the same issue.
