Description

Endpoint object in Uima AS should declare booleans as volatile to avoid possible race conditions. Due to java memory model, an unsychronized change of a boolean value in one thread may not be visible to another thread. Declaring a boolean as volatile fixes this without requiring explicit synchronization.
