java.lang.ClassCastException: class org.eclipse.jdt.internal.compiler.lookup.ArrayBinding cannot be cast to class org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding

[callain-mirakl]

The LSP cannot build my project anymore because of a ClassCastException. The class that causes the error is generated by jOOQ.
It seems related to the version 1.32.0. I've rollbacked to 1.31.0 and it works

Environment

• Operating System: macOs Sonoma 14.5
• JDK version:

openjdk 21.0.1 2023-10-17 LTS
OpenJDK Runtime Environment Zulu21.30+15-CA (build 21.0.1+12-LTS)
OpenJDK 64-Bit Server VM Zulu21.30+15-CA (build 21.0.1+12-LTS, mixed mode, sharing)

• Visual Studio Code version: 1.91.0
• Java extension version: 1.32.0

Additional Informations

[alexcormier]

We also ran into this; I submitted an issue to the compiler repo: eclipse-jdt/eclipse.jdt.core#2817.

[callain-mirakl]

Thank you @alexcormier
The issue is fixed in the compiler repository. How can we fixed it here?

[callain-mirakl]

It took me a bit of investigation to understand how things works here, but I understood that the JDT version is automatically upgraded when a new release of vscode-java is done.

The problem is fixed with the latest pre-release version of vscode-java. v1.36.2024102308 (pre-release)
But it is not fixed it the latest stable release 1.35.1. Until the next stable release I'm switching to pre-release versions.
