Description

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.
