False positive warnings and errors

[WillsterJohnson]

When loading a java project, the extension reports hundreds of warnings and errors. once those files are opened, the nonsenese warnings and errors disappear.
If at any point all java files are closed, the nonsense warnings and errors reappear.

The only way to get rid of them is to open every file they appear in.

Environment

• Operating System: MacOS 14.5
• Visual Studio Code version: 1.95.0
• Java extension version: 1.35.1

$ java -version
openjdk version "22.0.2" 2024-07-16
OpenJDK Runtime Environment Zulu22.32+15-CA (build 22.0.2+9)
OpenJDK 64-Bit Server VM Zulu22.32+15-CA (build 22.0.2+9, mixed mode, sharing)

Steps To Reproduce

1. Open a relatively large java project
2. observe nonsense errors and warnings

Dozens of warnings for file ArrayList.java

No issues found in file after opening

I am also suffering from this problem

Looking in the LS logs the following is seen:

Whenever the project is re-built/re-compiled this error is seen followed by many many others (presumably caused by this one)

This is a known bug and has been fixed in openjdk/jdk@0a58cff#diff-b0022dadcf17a9350521e4292b68668246c32423d90633ce91f8dc350eb78c70R277-R280

But as far as i can tell, is not available yet in JDK23-GA ?

I've tried running the Language Server with early access JDK24, but there are other incompatibilities that i don't have the time to look into. Neither is it really a good work around :(
