>Description:
_Jv_ResolvePoolEntry doesn't lookup methods in (abstract) superclasses that (didn't) implement an Interface method.
The following code shows the problem:
When compiled with "gcj -C *.java" and run with "gij C" it throws:
Exception in thread "main" java.lang.NoSuchMethodError: method A.m was not found.
at _Jv_ResolvePoolEntry(java.lang.Class, int) (/usr/local/gcc33/lib/libgcj.so.3.0.0)
at C.main(java.lang.String[]) (Unknown Source)
