A DESCRIPTION OF THE REQUEST :
Within bug id 4140870 a request was formulated for timeout on synchronized blocks. The solution proposed was to use concurrent.locks.ReentrantLocks.

This is not always applicable:

In case of third party libraries we have no way of changing the code from synchronized(){} to use the concurrent package.

We therefore request to add a VM attribute for example -DdeadlockTimeout, which would throw an exception if a dead lock is encountered for longer than a given time period.

JUSTIFICATION :
In case of third party libraries we have no way of changing the code from synchronized(){} to use the concurrent package.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
We therefore request to add a VM attribute for example -DdeadlockTimeout, which would throw an exception if a dead lock is encountered for longer than a given time period.
ACTUAL -
Currently the application just hangs.
