Answer a question

I am currently working on a Java project using the Java Extension Pack for VS Code. Thus plugin has been working for three weeks and now the auto completion has decided to stop for no reason.

Looking in the 'output' tab, I can see the following errors:

What's going on here and is there anything I can do to fix it?

Answers

The last version of "Language Support for Java(TM) by Red Hat" extension throws errors and break code completion.

Temporary solution is to go back to previous version of this extensions. This worked for me.

Note: I see new version is released this morning. I've installed it and problem is solved now.

So try to upgrade to 0.55.1 and see if it's solved now.
