I don't see the crash problem that Shelley is seeing, but I do see the test failing. If I put a sleep between the copy of the file and redeploy, then the test passes. | [ejort@warjort testsuite]$ svn diff | Index: src/main/org/jboss/test/jmx/test/UndeployBrokenPackageUnitTestCase.java | =================================================================== | --- src/main/org/jboss/test/jmx/test/UndeployBrokenPackageUnitTestCase.java (revision 78789) | +++ src/main/org/jboss/test/jmx/test/UndeployBrokenPackageUnitTestCase.java (working copy) | @@ -152,6 +152,8 @@ | | Files.copy(goodjar, thejar); | getLog().info("Redeploying testPackage: " + testPackage); | + | +Thread.sleep(10000); | | redeploy(testPackage); | Object home = getInitialContext().lookup("EntityA"); | So this is clearly either a caching issue inside the VFS/JDK or there is some issue with the Files.copy() not flushing properly to the file system so the server is seeing a corrupt file.
