CasMultiplier doesn't work for PEARs

The original code called process(aCas) and returned the EmptyCasIterator. Thus CASes produced were thrown away. The following is a two line change fix:

org.apache.uima.analysis_engine.impl.PearAnalysisEngineWrapper

public CasIterator processAndOutputNewCASes(CAS aCAS)
throws AnalysisEngineProcessException {

UIMAFramework.getLogger(this.getClass()).logrb(Level.FINE,
this.getClass().getName(), "processAndOutputNewCASes",
LOG_RESOURCE_BUNDLE, "UIMA_analysis_engine_process_begin__FINE",
new Object[]

{ this.ae.getAnalysisEngineMetaData().getName() });

CasIterator result = this.ae.processAndOutputNewCASes(aCAS); // FIXED LINE

UIMAFramework.getLogger(this.getClass()).logrb(Level.FINE,
this.getClass().getName(), "processAndOutputNewCASes",
LOG_RESOURCE_BUNDLE, "UIMA_analysis_engine_process_end__FINE",
new Object[] { this.ae.getAnalysisEngineMetaData().getName() }

);

return result; // FIXED LINE
}

Just the indicated lines are changed.
