WARNING: ThreadAnnotator worker thread not ready!

[Edward Johnson <ej...@coderyte.com>]

I am running a pipeline using the CPE gui.  One of my annotators is written in perl and the rest are in java.  Frequently (but not every time) when I run the pipeline I get an error message "WARNING: ThreadAnnotator worker thread not ready!" and the cpe gui stays in the "Initializing" stage indefinitely.  This only happens when there is a non-java annotator in the pipeline.

Has anyone seen this and is there a fix/workaround for it?

Thanks.
  Edward.

One suggestion is to run the same pipeline in base uima aggregate. Simplify
the deployment to a single thread and see if this problem occurs in simple
use case. Run it a couple of times to see if this has something to do with
the non-java annotator. If this works fine consistently the next thing is to
try to determine the source of the hang in the CPE. One way would be to
attach jConsole to the CPE's JVM and check threads to see which one is stuck
and where. Perhaps this will make it easier to determine the problem. Are
there any other messages in the log/console?
