Hi tejpal,
Can you add a testcase to the fix? I guess one is there in the JBS itself.

Hi All,
Please review the following fix for jdk14.
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 JDK-8030702
<https://bugs.openjdk.java.net/browse/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 JDK-8030702
<https://bugs.openjdk.java.net/browse/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.

Tejpal
