In Spectrum Oneclick if you change the „Look and feel” to “nimbus”, you will have the following problem:
The Alarm Title has a white font on white background so you will not see the Alarm Title
Release : 21.2.x
Component : Spectrum OneClick
OpenJDK bug https://bugs.openjdk.java.net/browse/JDK-8058704 that appears to be fixed in b11 that is recently resolved on 2021-08-12 22:13
Now, We are using AdoptOpenJDK which is built top of openJDK.
From AdoptOpenJDK site, the most recent version is jdk8u302-b08, provided link
jdk8u302-b08 is part of new spectrum release (21.2.4) but the issue still exists.
We need to wait for open JDK b11 build release and verify the same.
This will be corrected in a future Spectrum release when JDK will release a version that fixes the issue.
