Description

As part of the general effort to get UIMA performance better in highly multithreaded environments, find and remove unneeded synchronizations. One such example: the UIMAFramework code has a static method, getInstance(), which returns the value of a static field. There are no other synchronizations within this class, so I believe this can be removed.
