[Prasanta Sadhukhan]

> javax/swing/text/StyledEditorKit/4506788/bug4506788.java fails in ubuntu22.04 seems to fail in OCI system citing "Test failed"
> suggesting caret is not at expected place after text is typed, but I could not find any CI jobs having it failed.
> Anyway simplified the test and added stability fixes which made it pass now in several OCI systems..
