1) AssertionFailure "no ptr map found"
thrown from sun.jvm.hotspot.compiler.OopMapSet.updateRegisterMap(OopMapSet:265)

2) ClassCastException -- stated in previous update
thrown from sun.jvm.hotspot.jdi.ObjectReferenceImpl.countLockedObjects(ObjectReferenceImpl:186).

3) NullPointerException from sun.jvm.hotspot.runtime.CompiledVFrame.createStackValue (CompiledVFrame.java:181) --- linux , -server mode
