We have an issue that I am pretty sure is down to e4 and compatibility with e3 plugins, and I am at wits end how to debug any further.
We have developed an Eclipse plugin that has worked just fine across all releases since it was first released on juno, all the way through to neon. Now, on photon, Eclipse will hang on startup after our plugin has been installed after selecting a NEW workspace, or attempting to switch to a NEW workspace and restarting. It starts just fine if the active workspace is the same as when the plugin was installed. This is the same with p2 installations.
What triggers the hang is if either the file <workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi is missing, or it does not contain the entry:
<rootContext xmi:id="<something>" elementId="<pluginId>.actionSet" name="Auto::com.ecoscentric.cdt.actionSet"/>
where <something> is some hash key, and <pluginId> is our plugin Id. That is, if I remove the above line from a working workspace, Eclipse hangs on startup, or copy <workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi into a failed workspace, Eclipse starts.
Starting Eclipse with -debug -consoleLog, you see multiple exceptions every 5 seconds from various threads with the message:
Timeout after waiting 5 seconds to acquire the lock.
See also attached debug log.
jstack confirms there is a deadlock with various threads locked in various stages.
Debugging with Eclipse RCP does not help either - the Eclipse+plugin always fires up OK because the new workspace is adequately prepared. I am installing into eclipse-cpp-2018-09-linux-gtk-x86_64 (same issue existed with photon-R, but this all worked in releases of Eclipse prior to photon.)
I would appreciate any help or advice to figure out why our plugin causes photon to hang on startup with NEW workspaces. Googling around this issue all revolves around broken workspaces and deleting .lock or .fileTableLock files etc. None of these exist in the installed eclipse directory, and also obviously in the workspace directory because it was newly created. However, in a failed startup in a newly created workspace, the following files typically exist in the workspace:
<workspace>/.metadata/.lock
<workspace>/.metadata/.plugins/org.eclipse.epp.logging.aeri.ide/org.eclipse.epp.logging.aeri.ide.server/local-history.lucene60/write.lock
<workspace>/eclipse-workspace-16/.metadata/.plugins/org.eclipse.epp.logging.aeri.ide/org.eclipse.epp.logging.aeri.ide.server/http-cache.lucene60/write.lock
Thanks
