thanks for reporting the issue. I see the NPE is threw by the decompiler extension. Which Java decompiler extension do you install?

[rockxsj]

decompiler

Thanks for reply! The decompiler extension is dgileadi.java-decompiler, and version is v0.0.2

[testforstephen]

this issue should be duplicated with dgileadi/vscode-java-decompiler#8, i would suggest to move the issue to there for further discussion.

@testforstephen is there a conclusion here?

[testforstephen]

This is the issue from the decomplier extension, the language features not work in the decompiled code at the moment. Need improve the decompiler extension to make it better integrated with the Java tooling.

@rockxsj As we know, the extension cweijan.vscode-office will cause this error, see redhat-developer/vscode-java#1741 (comment).
