Created attachment 282603 [details] sample code & error On OSX, running eclipse 2020-03 (also 2020-06m1) with jvm extracted from Liberica 11.0.7 zipped package (not dmg or pkg https://download.bell-sw.com/java/11.0.7+10/bellsoft-jdk11.0.7+10-macos-amd64.zip). When I launch the app, the splash screen showed, prompted user to choose a workspace, then crashed with “No Java runtime present, requesting install.” in the console and a OSX Dialog asking for Java 6. This works fine when switched to use installed Liberica 11.0.7 via -vm in .ini file. Likely related to that. I have an OSX App (based on 2020-03) also with bundled Liberica 11.0.7 JRE from zipped package. It shows the same behavior. Splash screen followed by the “No Java… “ message. The program does step into ApplicationWorkbenchWindowAdvisor.preWindowOpen() and so on until some AWT modules are invoked in one of the plugins. I further narrowed it down to a particular case: java.awt.Font. Referencing this class triggers a chain reaction leads to sun.lwawt.macosx.LWCToolkit’s System.loadLibrary("awt”). I suspect this is what kill the app but there is no log or crash report generated to prove that. I also tested this by placing a dummy reference of this class as the first line in ApplicationWorkbenchWindowAdvisor.preWindowOpen(). Surely it killed the app right away. The crash stops if I remove any usage of java.awt.Font. For some reason, I can get the app to work with the same jvm by launching the app with java command instead of Contents/MacOS/launchfilename, something like $TARGET_PATH/Contents/java/jre/bin/java -XstartOnFirstThread -verbose:class -Xdebug --add-modules=ALL-SYSTEM -jar $TARGET_PATH/Contents/Eclipse/plugins/org.eclipse.equinox.launcher_1.5.700.v20200207-2156.jar -debug -verbose Of course, if I switch to use installed JVM, it works too. Please see screenshot for simple code snippet and the OSX error dialog.
