Description Randall Theobald CLA 2011-03-22 11:52:04 EDT 
Build Identifier: Eclipse version: 3.6.2.r362_v20110210 build: M20110210-1200

I am a performance analyst for an adopting product. I recently ran into some errors that I think denotes a lack of thread safety in WST. I have the following two exceptions at very close timestamps. They both failed in the same code. It hints at non-compatible concurrent access.

Please see if there is a way to prevent this from happening by some sort of locking.
