Exception error: Limit of jInternal Frames in NetBeans

There is a limit of jInternal frames on a jDesktopPane?
YES there is a limit of jInternal frames i.e. 20
Means you can add only 20 jInternal Frames on a jDesktop Pane. If you exceed the limit
then you see an event error or Class defination not find like that error:
