'To use the “java” command-line tool you need to install a JDK.' popup on macOS

I installed java-2020-12-M2 on a brand new Mac (macOS 10.15.7). Only JDKs installed so far were done via sdkman, that Eclipse happily ignores.

So Eclipse is started with the embedded JRE: 
-vm
/Users/fbricon/Dev/eclipses/java-2020-12-M2.app/Contents/Eclipse/plugins/org.eclipse.justj.openjdk.hotspot.jre.full.macosx.x86_64_14.0.2.v20200815-0932/jre/lib/libjli.dylib 

When opening https://github.com/eclipse-m2e/m2e-core/blob/master/org.eclipse.m2e.core/plugin.xml this popped up: 'To use the “java” command-line tool you need to install a JDK.' 

This is eerily similar to Bug #568634
