Description
If SA connector is used and debugger tries to use MonitorInfo provided by ThreadReference.ownedMonitorsAndFrames() ClassCastException is thrown:
java.lang.ClassCastException: sun.jvm.hotspot.jdi.MonitorInfoImpl cannot be cast to com.sun.jdi.MonitorInfo

To reproduce run script from attached archive:
>> run_sajdi.sh <path to the tested java> test05.Debuggee test05.Debugger

Example of test run:
>> run_sajdi.sh /set/vmsqe/jdk/7/build/latest/linux-i586/ test05.Debuggee test05.Debugger
Running debuggee: /set/vmsqe/jdk/7/build/latest/linux-i586//bin/java test05.Debuggee
