Rather than the debug agent checking if it has enabled JVMTI single stepping, instead it checks some fields in the ThreadNode that say if single stepping is pending, and it is for a STEP_INTO. If it is not STEP_INTO, then it can assume that no StepEvent will occur at the same location and therefor the MethodEntryEvent should not be deferred. So this limits the bug to only happening when doing a STEP_INTO. "
