java.lang.IllegalArgumentException Attempted to endRule & - java.lang.IllegalArgumentException Worker thread ended job: Classpath Update Job(29039), but still holds rule

Hi,
We have a multi-module Gradle-based Java Spring application. When trying to open it in Cursor IDE with the Language Support for Java plugin enabled, the project does not fully load.

We had a circular dependency issue which i reported in https://github.com/microsoft/vscode-gradle/issues/1659 and https://github.com/redhat-developer/vscode-java/issues/3986 but it seems with Language Support for Java(TM) by Red Hat plugin Version 1.41.0, our gradle sub projects are visible as expected, without circular dependencies reported and without weird project names.

But now, with Language Support for Java(TM) by Red Hat plugin Version 1.41.0, when i open my project even java projects are visible in JAVA PROJECTS view, the code is not loaded, not detected properly after waiting for some hours.

I see the following kind of errors logged for plugin. There are too many logged errors. I am putting here just some samples.

[Error - 11:56:38] 31 Mar 2025, 11:56:38 An internal error occurred during: "Classpath Update Job".
Attempted to endRule: null, does not match most recent begin: R/.  See log for trace information if rule tracing is enabled.

Our installed versions;
OS Version: macos 15.3.2 (24D81)
Gradle: 8.12.1
Java: OpenJDK 21.0.3 LTS
Spring Boot: 3.4.3
Cursor Version: 0.47.8 (Universal)
Language Support for Java(TM) by Red Hat plugin Version 1.41.0
vscode-gradle Extension Version: 3.16.4

It looks like the issue is related to latest Language Support for Java(TM) by Red Hat plugin Version 1.41.0 version.
Can you please have a look ?

Thanks in advance

Start by reproducing the multi-module Gradle project with the listed Java, Cursor, and Language Support for Java versions, then inspect the Classpath Update Job errors. Trace the reported path through JobManager.endRule, WorkManager.checkOut, and Workspace.endOperation. Done means the project loads correctly without the rule-mismatch and worker-thread errors.
