Description Moritz Eysholdt CLA 2010-05-29 07:56:37 EDT 
I'm getting this exception when running tests, e.g. 
org.eclipse.xtext.EcoreUtil2Test.testExternalFormOfEReference()
org.eclipse.xtext.mwe.ReaderTest.testLoadMatchNone()

The error only occurs when the test is run as plugin-test. Everything seems fine if the test runs as plain java junit test.

org.antlr.runtime.CharStream is on the class path three times:
/eclipse/plugins/org.antlr.runtime_3.0.0.v200803061811.jar
/de.itemis.xtext.antlr/antlr-generator-3.0.1.jar
/org.antlr/antlr-3.0.1.jar

Could this be a version incompatibility between the version of antlr we ship and the version of antlr from orbit?

Comment 1 Moritz Eysholdt CLA 2010-05-31 10:24:37 EDT 
Fixed by deleting antlr-generator-3.0.1.jar from de.itemis.xtext since this is exported by org.antlr.gen and removing exports of antrl.runtime from antlr.gen.
