[vscode] Language Support for Java crash frequently

[provide a description of the issue]
I use the theia platform which already uses the 'Language Support for Java' to realize the feature of LSP. I use single container (K8s Pod) to open a new theia server for every user, however, not only It is very slow, but the edit box also disrupted usually, especially several user online concurrently.

Environment

• Operating System:Linux version 5.13.12-1.el7.elrepo.x86_64 (gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2), GNU ld version 2.32-16.el7) SMP Tue Aug 17 10:49:05 EDT 2021
• JDK version: java version "11.0.10" 2021-01-19 LTS
• Visual Studio Code version: I use Theia(v1.26.0) platform which bases on VSCode
• Java extension version: Language Support for Java(TM) by Red Hat v1.1.0
• My Pod config is 6C, 16G memory

Steps To Reproduce

1. starting theia server with node: /usr/local/bin/node /opt/web/ws-63013/src-gen/backend/main.js -h 0.0.0.0 --plugins=local-dir:plugins --port 50008
2. opening browser to active the client with port 50008
3. import my project and then open a java file

I am sorry about cannot attach my project because it is owned by my company.

Current Result

The code completion stop work, if I type or do something in the window, the plugin seems reloading and diagnosis my project again, which will spend dozens of second to work again. It seems the plugin of Language Support for Java is incompatible with @jdt.ls(LSP)

there is another error if it helps: 'vscode java connection to server got closed. server will not be restarted'

Expected Result

It works smoothly and effectively, we cannot put the unreliable version online.

Additional Informations

The plugin reports out of memory occasionally, my setting of memory is "-Xmx2G -Xms1G"

Another issue is that the plugin throws 'org.eclipse.jface.text.BadLocationException: Offset > length: 66 > 0' error occasionally when I edit my code on window. Moreover, the performance of completion code is very slower than raw version of "jdt.ls + monaco editor" which we were using until now.
