[jbosside-dev] FW: Memory leak in DroolsIDE

Hey Marshall: Please forward this over to the rules guy. I found a memory leak in his code. The class RuleHelperActionDelegate ( svn<http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-ide/src...) has a memory leak. Specifically: the Delegate itself is responsible for deleting any and all created Menu widgets. In the current implementation, the getMenu(Control) method is as follows: Menu menu = new Menu( parent ); final Shell shell = parent.getShell(); addProjectWizard( menu, shell ); addRuleWizard( menu,shell ); addDSLWizard( menu, shell ); addDTWizard( menu,shell ); return menu; Clearly, new menu widgets are created each time and are never disposed of. A correct implementation of this interface is available at org.eclipse.wst.server.ui.internal.webbrowser.SwitchBrowserWorkbenchAction. Specifically, the getMenu(Control) method should first dispose of the last menu, then create the new ones. public Menu getMenu(Control parent) { setMenu(new Menu(parent)); //fillMenu(fMenu); initMenu(); return fMenu; } private void setMenu(Menu menu) { if (fMenu != null) { fMenu.dispose(); } fMenu = menu; } So... ... ... he needs to destroy his menus before creating new ones =]
