We should not use some short branches (T4 SPARC cbcond) in method InterpreterMacroAssembler::testinvocationcounterformdp() because in debug VM with Jvmti events enabled and CodeCache allocation far from runtime functions the code generated by callVM() and by following testbackedgecountforosr() is large. The distance to Lforward label can't be encoded into short branch instructions. Note: bug's synopsis is incorrect, I will change it. Thanks, Vladimir
