****************************************************************
With a lazy name space connection,
java.lang.ArrayIndexOutOfBoundsException is thrown when
multiple threads attempting to access a name space the first
time using JNDI APIs. That was because the call of getting an
initial context is not synchronized which it should be
since the initial context factory implementation is not
designed to be thread safe.
Problem conclusion
To prevent the ArrayIndexOutOfBoundsException, implemented a
synchronize block to synchronize the call of getting an
initial context.
