I frequently run UIMA-AS with scaled up AEs in the same jvm with no
problems. The UIMA-AS calls defineCasPool() once
when all AEs are instantiated.
The uima-core code that throws the exception is in
CasManager_impl.defineCasPool()
private synchronized void defineCasPool(UimaContext aRequestorContext,
String aRequestorContextName, int aMinimumSize,
Properties aPerformanceTuningSettings) throws
ResourceInitializationException {
* int poolSize = getCasPoolSize(aRequestorContextName, aMinimumSize);*
*if (poolSize > 0) {*
CasPool pool = (CasPool)
mRequestorToCasPoolMap.get(aRequestorContextName);
if (pool == null) {
// this requestor hasn't requested a CAS before
pool = new CasPool(poolSize, this, aPerformanceTuningSettings);
populateCasToCasPoolAndUimaContextMaps(pool, aRequestorContext);
mRequestorToCasPoolMap.put(aRequestorContextName, pool);
//register with JMX
registerCasPoolMBean(aRequestorContextName, pool);
} else {
* throw new
UIMARuntimeException(UIMARuntimeException.DEFINE_CAS_POOL_CALLED_TWICE,*
* new Object[] { aRequestorContextName });*
}
}
}
So it looks like something else is calling this method before UIMA-AS does.
You may need to run UIMA-AS in a debugger
to determine what is happening. Just set a break point in defineCasPool and
back trace the call.
