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

• JDK version:
  openjdk version "11" 2018-09-25

  OpenJDK 64-Bit Server VM (build 11+13-Debian-2, mixed mode, sharing)

• Visual Studio Code version:
  Version: 1.47.3
  Commit: 91899dcef7b8110878ea59626991a18c8a6a1b3e

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

Revisa el archivo vscode-java.error.txt adjunto y el stack trace de SemanticHighlightings, y luego reproduce el fallo abriendo cualquier archivo .java con las versiones indicadas de VS Code, JDK y la extensión. Determina por qué el servidor de lenguaje no se inicia y verifica que la apertura de un archivo Java se complete sin el error indicado.
