Bug 49655 StringIndexOutOfBoundsException on test failure [JUnit]
While testing the move to Ant 1.6.0 I was adjusting the org.eclipse.ant.core test suite (it had failures). I was reliably getting the following exception when test failures occurred: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.substring(String.java:1444) at org.eclipse.jdt.internal.junit.ui.TestRunnerViewPart.testFailed (TestRunnerViewPart.java:524) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient$7.run (RemoteTestRunnerClient.java:477) at org.eclipse.core.internal.runtime.InternalPlatform.run (InternalPlatform.java:813) at org.eclipse.core.runtime.Platform.run(Platform.java:457) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient.notifyTestFailed (RemoteTestRunnerClient.java:474) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient.access$16 (RemoteTestRunnerClient.java:471) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient$TraceProcessingState.r eadMessage(RemoteTestRunnerClient.java:125) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient.receiveMessage (RemoteTestRunnerClient.java:309) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient.access$30 (RemoteTestRunnerClient.java:308) at org.eclipse.jdt.internal.junit.ui.RemoteTestRunnerClient$ServerConnection.run (RemoteTestRunnerClient.java:235)
