JCompiler seems to load fine. I had to reinstall it once but it seems to work load fine now. But I get the following when actually trying to execute it OR when just trying to get to the JCompiler options dialog. Clues anyone? java.lang.NullPointerException at java.util.StringTokenizer.(Unknown Source) at java.util.StringTokenizer.(Unknown Source) at javacore.AbstractClasspathSource.loadClassNames(AbstractClasspathSource.java:476) at javacore.AbstractClasspathSource.init(AbstractClasspathSource.java:455) at javacore.DefaultClasspathSource.(DefaultClasspathSource.java:53) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at bsh.Reflect.constructObject(Reflect.java:668) at bsh.BSHAllocationExpression.constructObject(BSHAllocationExpression.java:123) at bsh.BSHAllocationExpression.objectAllocation(BSHAllocationExpression.java:114) at bsh.BSHAllocationExpression.eval(BSHAllocationExpression.java:62) at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:102) at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:47) at bsh.Interpreter.eval(Interpreter.java:641) at bsh.Interpreter.eval(Interpreter.java:731) at bsh.Interpreter.eval(Interpreter.java:720) at org.gjt.sp.jedit.BeanShell._eval(BeanShell.java:446) at org.gjt.sp.jedit.BeanShell.eval(BeanShell.java:410) at org.gjt.sp.jedit.ServiceManager$Descriptor.getInstance(ServiceManager.java:321) at org.gjt.sp.jedit.ServiceManager.getService(ServiceManager.java:264) at javacore.JavaCorePlugin.getClasspathSource(JavaCorePlugin.java:71) at javacore.JavaCorePlugin.getClasspathSource(JavaCorePlugin.java:57) at jcompiler.options.JCompilerOptionPaneCompiler._init(JCompilerOptionPaneCompiler.java:414) at org.gjt.sp.jedit.AbstractOptionPane.init(AbstractOptionPane.java:108) at jcompiler.options.JCompilerOptionDialog.(JCompilerOptionDialog.java:107) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at bsh.Reflect.constructObject(Reflect.java:668) at bsh.BSHAllocationExpression.constructObject(BSHAllocationExpression.java:123) at bsh.BSHAllocationExpression.objectAllocation(BSHAllocationExpression.java:114) at bsh.BSHAllocationExpression.eval(BSHAllocationExpression.java:62) at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:102) at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:47) at bsh.BSHBlock.evalBlock(BSHBlock.java:130) at bsh.BSHBlock.eval(BSHBlock.java:80) at bsh.BshMethod.invokeImpl(BshMethod.java:349) at bsh.BshMethod.invoke(BshMethod.java:246) at bsh.BshMethod.invoke(BshMethod.java:171) at org.gjt.sp.jedit.BeanShell.runCachedBlock(BeanShell.java:523) at org.gjt.sp.jedit.BeanShellAction.invoke(BeanShellAction.java:76) at org.gjt.sp.jedit.gui.InputHandler.invokeAction(InputHandler.java:229) at org.gjt.sp.jedit.jEdit$3.invokeAction(jEdit.java:2910) at org.gjt.sp.jedit.EditAction$Wrapper.actionPerformed(EditAction.java:216) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$ForwardActionEvents.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.AbstractButton.doClick(Unknown Source) at javax.swing.plaf.basic.BasicMenuItemUI.doClick(Unknown Source) at javax.swing.plaf.basic.BasicMenuItemUI$MouseInputHandler.mouseReleased(UnknownSource) at java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)
