Created attachment 282324 [details] JFR dump of Eclipse hanging on 77% of building a submodule My Eclipse tried to rebuild my workspace after saving a HTML file, and got to 77% of one of our submodules. The project is a roughly 1M lines of Java code, Maven based project with 60-70 submodules. I've attached a JDK Flight Recording of 5 minutes of data capture of the "Profile" settings. This includes 5 stack traces. The symptom is that the build hangs on 77%. When you open up the dialog for progress, you can't stop the build. Eclipse effectively hangs, even though some UI processing seems to come through. This is not limited to macOS, as this also apparently happens with the Windows installation of a coworker, anecdotally also at 77%.
Can you please attach jstack dump from the hanging Eclipse? I believe jfr is not available for RHEL.
Also please provide used Eclipse / JDK versions.

You can open it with e.g. Zulu Mission Control: https://www.azul.com/products/zulu-mission-control/#block-download I'll also add the stack dumps as comments
Ok, the stack dumps are larger than bugzilla allows, so I'll attach them.
Created attachment 282325 [details] First stack dump
Created attachment 282326 [details] Second stack dump
Created attachment 282327 [details] Third stack dump
Created attachment 282328 [details] Fourth stack dump
Created attachment 282329 [details] Fifth stack dump
Probably m2e problem, this thread below blocks all workspace tasks, and UI unfortunately requested lock on workspace for saving the file (but I believe you should see progress dialog where you can cancel the "user waiting task"). Since this is m2e & maven, we should move it to the right product, it's not JDT/Platform.

Eclipse m2e is moving away from this bugs.eclipse.org issue tracker to https://github.com/eclipse-m2e/m2e-core/issues/ instead. If this issue is relevant to you, your action is required. 0. Verify this issue is still happening with latest Eclipse Platform and m2e release if issue has disappeared, please change status of this issue to "CLOSED WORKFORME" with some details about your testing environment and how you did verify the issue; and you're done if issue is still present when latest release: * Create a new issue at https://github.com/eclipse-m2e/m2e-core/issues/ ** Use as title in GitHub the title of this Bugzilla ticket (may include the bug number or not, at your own convenience) ** In the GitHub description, start with a link to this bugzilla ticket ** Optionally add new content to the description if it can helps towards resolution ** Submit GitHub issue * Update bugzilla ticket ** Add to "See also" property (up right column) the link to the newly created GitHub issue ** Add a comment "Migrated to <link-to-newly-created-GitHub-issue>" ** Set status as CLOSED MOVED ** Submit All issues that remain open will be automatically closed next week or so. Then the m2e component for m2e will be made read-only.
