[jdk11u-dev] RFR: 8233569: [TESTBUG] JTextComponent test bug6361367.java fails on macos

[Jonathan Dowland]

This is a nearly-trivial backport of a test-only bug fix for 11u. Oracle backported this in 11.0.13-oracle . It applies clean except for ProblemList.txt.

Prior to backport, the test in 11u passes for me on macos anyway. Reading a comment by Philip Race [1], the underlying bug was believed to have been fixed by 225144 which is already backported. However they continued to see some test failures after 225144, which were presumably eventually addressed by this patch which followed it.

Please consider either for 11u or I request the bug be labelled jdk11u-na.

Thanks!
