Jerry Cwiklik updated UIMA-1223:
--------------------------------
Attachment: uimaj-as-core-UIMA-1223-patch.txt
uimaj-as-activemq-UIMA-1223-patch.txt
Added custom Thread factory to the ThreadPoolTaskExecutor that creates threads
which Initialize AEs in a primitive controller. Subsequently, a thread that
initialized AE will be called to call process method on that AE instance.
Modified primitive controller to create resource specifier in the same thread
that will create AE instance.
Modified UimaDefaultMessageListenerContainer, to wait for all threads to stop.
> Annotators should be initialized in the same thread that their process method
> will later be called on

> It is more convenient if an annotator is initialized on the same thread that
> it is later called on. Some components may use thread-local data and they
> won't work in UIMA-AS currently. Another advantage of doing the
> initialization in the processing thread is that you could initialize multiple
> instances of the annotator in parallel instead of sequentially, which may be
> faster for a multi-core machine.
