back port fix for - JBSEAM-4334 - Useless lock in Initialization.redeploy

Initialization.redeploy has the following bit of code:

ReentrantLock lock = new ReentrantLock();
if (lock.tryLock(500, TimeUnit.MILLISECONDS))

This lock does not provide any level of protection, as every thread creates a new lock and then locks it. This will only cause potential problems in debug mode.
