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
  Date: 2020-07-23T15:51:39.791Z
  Electron: 7.3.2

  OS: Linux x64 4.15.0-29deepin-generic

• Java extension version:
  v0.65.0

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

检查附加的 vscode-java.error.txt 和 SemanticHighlightings 堆栈跟踪，然后使用列出的 VS Code、JDK 和扩展版本打开任意 .java 文件来重现崩溃。确定 language server 无法启动的原因，并验证打开 Java 文件时不会出现所报告的错误且操作能够完成。
