I receive the following error using WSAD 5.1.0 only while starting the local test environment in debug mode.
Could not be defined due to: LinkageError while defining class: com.objectspace.jgl.Map Could not be defined due to: LinkageError while defining class: com.objectspace.jgl.Container Could not be defined due to: (com/objectspace/jgl/Container) method cannot be both abstract and strict at offset=631 This is often caused by having a class defined at multiple locations within the classloader hierarchy. Other potential causes include compiling against an older or newer version of the class that has an incompatible method signature. Dumping the current context classloader hierarchy: ==> indicates defining classloader  com.ibm.ws.classloader.CompoundClassLoader@24b924b9 Local ClassPath: O:\webdev\MKS\sandboxes\ze_sandbox\QW Gift\webApplication\WEB-INF\classes; Delegation Mode: PARENT_FIRST ==> com.ibm.ws.classloader.JarClassLoader@1422415048 Local Classpath: ... : PARENT_FIRST  com.ibm.ws.classloader.ExtJarClassLoader@1534942077 Local ClassPath: ... ; Delegation Mode: PARENT_LAST  com.ibm.ws.classloader.ProtectionClassLoader@63926392  com.ibm.ws.bootstrap.ExtClassLoader@7b507b5  sun.misc.Launcher$AppClassLoader@1a1a1a1a  sun.misc.Launcher$ExtClassLoader@3f243f24 ---Original exception--- java.lang.ClassFormatError: (com/objectspace/jgl/Container) method cannot be both abstract and strict at offset=6 Please help!
