Description

The following Code (see attached proxy-red.zip)

ProxyFactory f = new ProxyFactory();
f.setTargetClass(JCas.class);
f.getProxy();

JCas jCas1 = JCasFactory.createJCas(new String[] {});
jCas1.setDocumentText("test text"); // ==> ArrayIndexOutOfBoundsException

is throwing the following exception (see attached exception.txt)

java.lang.ArrayIndexOutOfBoundsException: -1
at ....FeatureStructureImplC._setIntValueCommon(FeatureStructureImplC.java:1636)

WORKAROUND (see attached proxy-green.zip)
Creating a regular JCas before fix the problem  (without using the created JCas)

JCasFactory.createJCas(new String[] {}); 

ProxyFactory f = new ProxyFactory(); 
f.setTargetClass(JCas.class); 
f.getProxy(); 

JCas jCas1 = JCasFactory.createJCas(new String[] {}); 
jCas1.setDocumentText("test text"); // ==> No exception
