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?
