Error connecting to server

Hi,
I've installed the extension for first time, and when it starts it shows an error "The Language Support for Java server crashed".
It opens the server logs indicating:
java.lang.IllegalAccessError: tried to access method org.eclipse.jdt.ls.core.internal.highlighting.SemanticHighlightings$AutoboxHighlighting.()V from class org.eclipse.jdt.ls.core.internal.highlighting.SemanticHighlightings

I've tried disabling semantic highlighting, and cleaning the workspace w/out success.

Environment

• Operating System:
  linux debian base distro : Linux XXXX 4.15.0-29deepin-generic

Steps To Reproduce

1. Install VSCode and the extension
2. Open any .java file, in the bottom right there's a spinning circle that ends up showing the error

I am attaching the log from the server. Please let me know if I am missing any useful information.

Additional Informations

Not sure if it adds any context, but I initially got the Java Extension Pack by sync configurations from another windows based vscode. I use "Settings Sync" extension. After getting this issue, I manually removed these packages and installed only the Language Support one but the issue persists.
vscode-java.error.txt

Esamina il file vscode-java.error.txt allegato e lo stack trace di SemanticHighlightings, quindi riproduci il crash aprendo un qualsiasi file .java con le versioni indicate di VS Code, JDK ed estensione. Determina perché il language server non si avvia e verifica che l’apertura di un file Java venga completata senza l’errore segnalato.
