Bug 62503 Classloader problem with older versions of JUnit [JUnit]
Reported: 2004-05-17 12:34:32 | Status: resolved fixed

I have a project with a version 3.6 junit.jar on the classpath. In 3.0M8 when I run a test with an assertEquals() that fails, I get this error: java.lang.NoClassDefFoundError: junit/framework/ComparisonFailure at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.addFailure(RemoteTestRunner.java:533) at junit.framework.TestResult.addFailure(TestResult.java:46) at junit.framework.TestResult.runProtected(TestResult.java:127) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:131) at junit.framework.TestSuite.runTest(TestSuite.java:173) at junit.framework.TestSuite.run(TestSuite.java:168) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:410) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:294) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:182) Exception in thread "main" This used to work with Eclipse 2.1 (which also had JUnit 3.8.1 built in), and it disappears when I upgrade my copy of junit.jar to 3.8.1 to match the Eclipse one.
