[Springframework-rcp-dev] [Spring-JIRA] Commented: (RCP-611) "OutOfMemoryError" exception occurs after the popup menu has been shown repeatedly

[Lieven D. (JIRA) <no...@sp...>]

    [ https://jira.springsource.org/browse/RCP-611?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=46850#action_46850 ] 

Lieven Doclo commented on RCP-611:
----------------------------------

Also, recreating the popup every time you right click isn't the best option. Normally your listener will hold an instance of that popup and reuse that popup when called. 
Normally, you're creating something like this:
{code}
public class MyMouseAdapter extends MouseAdapter
{
    private JPopupMenu menu;

    public MyMouseAdapter(CommandGroup group)
    {
        menu = commandGroup.createPopupMenu();
    }

    public void mouseReleased(MouseEvent e) {
        if (e.isPopupTrigger()) {
            menu.show(table, e.getPoint().x, e.getPoint().y);
        }
    }
}
{code}

But in any case I'll take a look at the weakhashmap issue
