line 2340: Error: Overloading ambiguity between "klassOop::operator

1 Error(s) detected.
Failure occurs at code added as part of:
7017732: move static fields into Class to prepare for perm gen removal
http://hg.openjdk.java.net/jdk7/hotspot-rt/hotspot/rev/c7f3d0b4570f
Failing code:
2340 if (real_klass && real_klass->klass_part()->oop_is_instance()) {
Likely cause:
real_klass needs to be a pointer-type in the "if" expression. In non-debug it is. In debug it's not and so we need to apply a conversion operator. The compiler is complaining that there are two possible conversion operators that apply.
Suggested fix:
Both cast operators are functionally equivalent so forcing resolution to either should be fine. It should be easier to force (void*) as it doesn't depend on whether it is a fastdebug build or not. So suggested trying:
if ( ((void*)real_klass) && ... )
