Background not refreshed when painting over a transparent JFrame

FULL PRODUCT VERSION :
openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-8u141-b15-3~14.04-b15)
OpenJDK 64-Bit Server VM (build 25.141-b15, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Linux Wall-E 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
The best is to check this link to understand the problem : https://stackoverflow.com/questions/46273464/background-not-refreshed-when-painting-over-a-transparent-jframe

Basically, the background of the JFrame is not refreshed despite calling repaint() when the JFrame is transparent. The bug seems to affect only the jvm for GNU/Linux as it could not be reproduced under MacOS.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
There is a test case at https://stackoverflow.com/questions/46273464/background-not-refreshed-when-painting-over-a-transparent-jframe

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The "text" label should be moving around the frame
ACTUAL -
The "text" label is painted over the frame but previously painted text are never cleared.

REPRODUCIBILITY :
This bug can be reproduced always.
