The fix look good to me. Some points about test case.
1. No need for author tag. This is not followed now. 2. The test case name should be something meaningful instead of bug***. 3. You should not need the GridBagConstraints code anywhere to reproduce the issue. You should remove this.

Regarding the test, dispose() should be called under EDT, just as you have done for createAndShowGUI().Also, I don't think createGridBagLayout() code is necessary to recreate the issue.

Bug : https://bugs.openjdk.java.net/browse/JDK-8190763 Webrev : http://cr.openjdk.java.net/~trebari/swing/8190763/webrev0/ Issue : This issue is a regression of https://bugs.openjdk.java.net/browse/JDK-8030702. When UndoableEditEvent.getEdit() is casted to CompoundEdit, it throws class cast exception. Fix : In HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8030702"JDK-8030702 a new class DefaultDocumentEventUndoableWrapper was introduced. UndoableEditEvent.getEdit() returns an object of DefaultDocumentEventUndoableWrapper and when it is casted to CompoundEdit it throws class cast exception because it doesn’t inherit CompoundEdit. Before the fix of HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8030702"JDK-8030702 , UndoableEditEvent.getEdit() used to return an object of DefaultDocumentEvent which inherits CompoundEdit so the class cast exception was not thrown. The solution is to make DefaultDocumentEventUndoableWrapper a subclass of DefaultDocumentEvent. Testing : I have tested it on Mac, Windows and Ubuntu. Regards Tejpal
