mmadmin: exportDataRoles gives NPE if no roles present for VDB - Should throw better exception. ----------------------------------------------------------------------------------------------- Key: TEIID-398 URL: https://jira.jboss.org/jira/browse/TEIID-398 Project: Teiid Issue Type: Bug Components: Tools Affects Versions: 6.0.0 Environment: fedora 10 running 5.5.2GA Reporter: Paul Nittel Assignee: Ramesh Reddy Priority: Minor Fix For: 6.1.0 While creating mmadmin tests for NIAP, I found that attempting to export roles from a VDB with no data roles, got an NPE. It should be getting a more meaningful exception. exportDataRoles("NiapWebVdb","2","/home/pnittel/mmx/552niap/TestMmadmin/testroles.xml"); // Error: // Uncaught Exception: Method Invocation ObjectConverterUtil.write : at Line: 600 : in file: URL: jar:file:/home/pnittel/mmx/552niap/tools/lib/mmadmin.jar!/scripts/serveradmin.bsh : ObjectConverterUtil .write ( currentContext ( ) .internalAdmin .exportDataRoles ( vdbName , vdbVersion ) , filename ) Called from method: exportDataRoles : at Line: 1 : in file: <unknown file> : exportDataRoles ( "NiapWebVdb" , "2" , "/home/pnittel/mmx/552niap/TestMmadmin/testroles.xml" ) Target exception: java.lang.NullPointerException java.lang.NullPointerException at com.metamatrix.core.util.ObjectConverterUtil.write(ObjectConverterUtil.java:121) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at bsh.Reflect.invokeMethod(Unknown Source) at bsh.Reflect.invokeStaticMethod(Unknown Source) at bsh.Name.invokeMethod(Unknown Source) at bsh.BSHMethodInvocation.eval(Unknown Source) at bsh.BSHPrimaryExpression.eval(Unknown Source) at bsh.BSHPrimaryExpression.eval(Unknown Source) at bsh.BSHBlock.evalBlock(Unknown Source) at bsh.BSHBlock.eval(Unknown Source) at bsh.BshMethod.invokeImpl(Unknown Source) at bsh.BshMethod.invoke(Unknown Source) at bsh.BshMethod.invoke(Unknown Source) at bsh.Name.invokeLocalMethod(Unknown Source) at bsh.Name.invokeMethod(Unknown Source) at bsh.BSHMethodInvocation.eval(Unknown Source) at bsh.BSHPrimaryExpression.eval(Unknown Source) at bsh.BSHPrimaryExpression.eval(Unknown Source) at bsh.Interpreter.run(Unknown Source) at com.metamatrix.script.shell.MMAdmin.main(MMAdmin.java:50)
