Environment: macOS High Sierra (10.13.3) === Eclipse IDE for Java Developers Version: Photon Milestone 5 (4.8.0M5) Build id: 20180314-2134 === org.eclipse.jdt.launching bundle is from: 3.10.0.v20180303-2257 === Eclipse itself running on a JDK 1.8.0_161 (In reply to Martin Lippert from comment #0) > I have the simplest Java app around: > > package javademo; > > public class MyMain { > > public static void main(String[] args) { > System.out.println("Hello World!"); > } > > } > > > It is configured for JDK 1.8. > > => launching this on JDK 1.8 JRE/JDK works > => launching this on JDK9 (9.0.4) fails with this message: > > === > > Error occurred during initialization of boot layer > java.lang.LayerInstantiationException: Package > jdk.internal.jimage.decompressor in both module jrt.fs and module java.base > > === > > Switching the project to have JDK9 as the runtime JRE on the classpath > (instead of the JDK1.8) fixes the issue. Now you got me confused: the error happens when you launch on JDK9 and it can be fixed by switching to JDK9??

Perhaps you have a mix of both 1.8 and 9 System libraries on the runtime classpath? Hint: after the (failed) launch: go to the Debug View, select the second node, its properties contain the full command line that was used for launching. What's it say? @Sarika, maybe I can sell stick notes with this hint ;p (In reply to Stephan Herrmann from comment #2) > (In reply to Martin Lippert from comment #0) > Now you got me confused: the error happens when you launch on JDK9 and it > can be fixed by switching to JDK9?? Here is the matrix of what works and what doesn't: - project configured with 1.8, launched on JDK 1.8: works - project configured with 1.9, launched on JDK 9: works - project configured with 1.8, launched on JDK 9: BOOOOOOM... And it seems to be 100% reproduceable... :-) (In reply to Stephan Herrmann from comment #3) > (In reply to Stephan Herrmann from comment #2) > > (In reply to Martin Lippert from comment #0) > Hint: after the (failed) launch: go to the Debug View, select the second > node, its properties contain the full command line that was used for > launching. What's it say? Command Line: /Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/bin/java -Dfile.encoding=UTF-8 -p /Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/lib/jrt-fs.jar -classpath /Users/mlippert/Documents/eclipse-workspace-issue-launch-jdk9-jdk8/javademo/bin javademo.MyMain (In reply to Stephan Herrmann from comment #3) > @Sarika, maybe I can sell stick notes with this hint ;p What's the rate :) Any way I checked it is getting patched -p C:\Eclipse\Downloads\JDK\jdk-9\lib\jrt-fs.jar I see it happening on 4.7.3 also.

I don't think that will impact but adding Jay to this, so that he can test this if breaks and report here.

At the moment, that fix is not going anywhere :( But it will have an impact, but I already see what needs to be done. And without that fix, I don't think Sarika has a choice anyway.

I have the simplest Java app around: package javademo; public class MyMain { public static void main(String[] args) { System.out.println("Hello World!"); } } It is configured for JDK 1.8. => launching this on JDK 1.8 JRE/JDK works => launching this on JDK9 (9.0.4) fails with this message: === Error occurred during initialization of boot layer java.lang.LayerInstantiationException: Package jdk.internal.jimage.decompressor in both module jrt.fs and module java.base === Switching the project to have JDK9 as the runtime JRE on the classpath (instead of the JDK1.8) fixes the issue. This is a major regression compared to Oxygen.2 (tested that, too). Launching a JDK1.8-based project on a JDK 1.8 and a JDK 9 works both out-of-the-box.
