After I upgraded Jenkins to 2.303.2, I'm seeing an alert as below. J. I think Java 11 is OpenJDK and we are using java 1.8.0_301. Is Java 1.8 no longer supported ? Any inputs are really appreciated. TIA

Jenkins continues to support Java 8.  We recommend Java 11.

See for more details on the rationale for that transition.

Somewhere it states that not all plug-ins support Java 11 also.

Good point.  More details on the transition to Java 11 are included in the 2.303.1 upgrade guide.  The upgrade guide includes a list of plugins known to be incompatible with Java 11.

I haven't tried switching yet.  Any concerns about switching to 11 and then rolling back to 8 if there is a problem?  Guessing no, but thought I'd ask...
