There is a lot of images held by form editor classes. Total retained size of images is 170 MB. All big images are there several times. Please investigate if those duplicities can be removed.
The memory held by images should be significantly improved by the fix in bug 251623. But the actual OOME here is from painting a tabbed pane with no obvious relation to GUI builder.
