Description Vladimir Kvashin 2006-08-03 11:46:34 UTC 
This happened several times on multiprocessor Sparks. It's hard to tell whether
it's connected with multiple processor presence or not.

Warning: Cannot process more work than scheduled. Progress handle with name
"Parsing clucene ..." has requested progress to workunit no.1 but the total
number of workunits is 0. That means the progress bar UI will not display real
progress and will stay at 100%.

Comment 1 Vladimir Kvashin 2006-08-03 11:48:16 UTC 
I've got this in a single parser thread situation.
Comment 2 julieg 2006-09-20 17:51:37 UTC 
It is reproducable when more then 1 thread is created. 
If set up -J-Dcnd.modelimpl.parser.threads=1  exception disappeared.

This bug blcoks QA's functinal testing on any muti-cpu machine.
Comment 3 Alexander Simon 2006-09-21 14:58:33 UTC 
-work around redundant progress incrementation
-synchronize progress access
