46 Random failing test CodeCompletionTest, JavadocCompletionTest, TypeCompletionTest since I20230824-0400

https://download.eclipse.org/eclipse/downloads/drops4/I20230824-0400/testresults/html/org.eclipse.jdt.text.tests_ep429I-unit-cen64-gtk3-java17_linux.gtk.x86_64_17.html

All are very similar, is if they are unable to find JDK classes

I wonder if that has relationship to the "DetectVMInstallationsJob" job / similar to https://github.com/eclipse-jdt/eclipse.jdt.core/issues/1190
