****************************************************************
In the code changes of 
PQ74375 and the webcontainer code,
there is a window in the code which could result in the
NullPointer Exceotions being thrown.
Problem conclusion
Code is changed so there is better synchronization to address
the NullPointerException.
Temporary fix
Fix sent to L2.
