Project does not contain any main class after update to 1.26.0

[bearArthurAog]

After update to 1.26.0 cannot run/debug java project using spring boot dashboard in vscode. Downgraded to 1.25.1 works fine.

Environment

• Operating System: Windows 11
• JDK version: graalvm-jdk-17.0.8+9.1
• Visual Studio Code version: 1.85.1
• Java extension version: 1.26.0

Steps To Reproduce

1. Update to 1.26.0
2. Run java projects either from JAVA PROJECTS tab in EXPLORER or Spring boot dashboard.

Exception appears here - https://github.com/microsoft/java-debug/blob/f8da9e2e2f55a2cefaf658ae24154c784eaa113e/com.microsoft.java.debug.plugin/src/main/java/com/microsoft/java/debug/plugin/internal/ResolveMainClassHandler.java#L156

java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0 at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getType(LookupEnvironment.java:1725)

Current Result

Project does not contain any main class ..

Expected Result

Runs as before

Additional Informations

I have multiple projects configured with workspace file containing lauch configs

I am running into the same issue. Did you ever get a resolution aside from keeping the version at 1.25.1?
