Re: Deadlock in Java9.getDefaultImportClasses() ?

The application uses thymeleaf templating engine that uses groove under the hood. The application does not respond to request that require a template to be rendered. Looking at the stacktrace did not give us any hint what is causing this. In the profiler it looks like a lot of time is spent waiting in Java9.getDefaultImportClasses() method. We could not find any code in there or in ClassFinder.find() that looks like it could cause a dead lock. When attaching the debugger and adding some break points in Java9.getDefaultImportClasses() it did work 🤷♂️. This is really weird. Java, Groovy and thymeleaf versions are the same? What Groovy version are you using btw? What version of Java? The only thing that we could see that is different between a working setup and a non-working one is the updated Kubernetes with updated node images using a newer linux kernel. No idea how this could impact the code. The linux kernel should not impact that unless it is a bug in Java. Does anyone have an idea what could cause this or what we could do to identify the cause of the dead lock? I attached a screenshot of the profiler. I would be nice to know the line number, then we know at least which of the 3 possible supplyAsync().get() fails. I was thinking maybe this can happen if there is an exception... but normally get() should produce an ExecutionException in that case. Right now I am a bit clueless bye Jochen
