A DESCRIPTION OF THE REQUEST :
As described in Bug ID 7178072, the java.util.regex Matcher is not interruptable and it has to be interruptable allowing to implement multi-threaded matching allowing the thread creator to interrupt the matching process in case it decides it deals with a degenerative case.

JUSTIFICATION :
  Bug ID 7178072 is more an enhancement than a bug and I would like to vote for this enhancement request.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
If run in a separate thread, the Matcher should check if the thread it is running on has been interrupted (Thread.isInterrupted()).
ACTUAL -
The matcher doesn't check Thread.isInterrupted()

---------- BEGIN SOURCE ----------
See Bug ID 7178072: we must not be forced to use Thread.stop() - which we have to if the Matcher continues to ignore Thread.isInterrupted()
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Thread.stop() - which is an inacceptable workaround, in fact.
