{code}
With lot of activity this can spam the logs reducing visibility of real errors in production logs.
For this, i proposed to add a last check within the synchronized method before inserting the lock, on which the fk constraint error is thrown.
This avoiding the error, if no other method in OFBiz insert data in `ServiceSemaphore` table...
A second patch is provided to add javadoc and trivial refoctoring
