Exception in Language Server console on Eclipse startup

Trying to investigate as per https://github.com/spring-projects/sts4/issues/340#issuecomment-573036075

I enabled the Spring Language Server console and restarted my Eclipse 2019-12 instance (with STS4 installed on top of it).

In my Language Server console I get the following exception (three times):

java.util.concurrent.TimeoutException: Did not observe any item or terminal signal within 5000ms in 'ignoreThen' (and no fallback has been configured)

The whole log is here, from start. Please ignore the exception regarding Gradle, I will open a separate issue for it.

What is this TimeoutException for? Is it a real error or just a warning of something that was recovered later?

Hi Martin, thank you for your support! I agree this can be closed now, the original issue was found and fixed. I’m not seeing other issues here, but to be honest I’m not using this tooling a lot in these days (it depends a lot on the tasks I’m working on). If I find something else, I will report back.

Thanks again for your support and kindness. I think you at Spring/Pivotal are an example to follow for the developer community.

Alex and I have worked a bit more on this and found that a significant delay was being caused by some code that is sorting projects for initial classpath events. This code contained some Display.syncExec call which, even in a small workspace with just a single trivial project can block execution for multiple seconds.

We have reworked this code a bit based on a idea from Alex to use FileBuffers instead of open editors. The advantage of this is that it can be done easily without using api calls that need to be executed on the UI thread.

We are pretty confident that we have pinpointed the root cause of the delay causing the timeout and adressed it.

See here: https://github.com/spring-projects/sts4/commit/17232e5a263b68182dc366134ccdf9e1deac6ff7

@martinlippert It does mean that we no longer able to determine all the open editors at startup or distinguish between the ‘main’ editor and others. During startup FileBuffers seems to instead correspond to editors who’s text is currently visible (so typicaly the top editor in a stack of editor tabs only).

I think this similar in ‘spirit’ to what the old project sorter was trying to do, but it is not functionally equivalent.

However, Alex and I felt that the syncExec in the old implementation causes too much problems to keep it (this is not the first time I am looking at that specific syncExec call as the culprit for some UI-thread blocking misbehavior, last time it was resolved by making the sorter a bit more lazy, but that seems to have only pushed the problem further down a bit rather than really solve it.

I’m inclined to close this issue as ‘resolved’ now. Perhaps Mauro can give the latest CI build a go still. (I don’t expect it to behave too much different as bumping the timeout from 5 to 10 seconds that Martin did already seemed to solve it too). About all I would expect is that perhaps startup may seem a little faster though I doubdt it will be noticeable.
