> Fix For: 2.4.0AS
>
>
> UIMA CasCreationUtils throws NPE from setupTypePriorities() when UIMA AS
> scales AEs in multiple threads. The NPE is due to thread safety issue in UIMA
> caused by lazy initialization of CAS pools. Seems to be triggered when large
> type system is used. Synchronize UIMA AS
> org.apache.uima.aae.EECasManager_impl.defineCasPool() to make sure only one
> thread at a time executes the code.
