'textDocument/didChange' never called with Java (org.eclipse.lsp4e.java)

[angelozerr]

I have a simple Java project with two classes. It seems that there is an error on Server side (with JDT Language Server). When I open a Java file, I have this error in the console:

!MESSAGE org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Internal error, please look at the server's logs.
!STACK 0
java.util.concurrent.CompletionException: org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Internal error, please look at the server's logs.

Completion, hover, etc is working, but 'textDocument/didChange' is never called because DocumentContentSynchronizer is never called.

@mickaelistria I think it's a bug for lsp4e, but I create here since bugs is found for Java support.

@angelozerr Can you check what is in your JDT LS log file? The file should be in data folder in the server directory. If you are using this integration from sources then it will be in plugin directory.

@angelozerr Can you check what is in your JDT LS log file?

Yes I have tried to see it insode the data/.metadata/.log but don't helpful traces.

Here traces when I open a simple Java file:
