[lworld] RFR: 8248163: jdb crashes when invoking "lock" command on inline class

[Frederic Parain]

Please review this patch which fix an issue with the JVMTI method GetObjectMonitorUsage() and inline types.
The behavior of the method when called on an inline type instance is to return a valid result and not throwing an
exception. The result will always show that the monitor is not locked and has never been locked.

A unit test has been added to cover this case.

Thank you,

Fred
