Unable to view beans for multiple modules in version v1.55

[Joshuahope]

Version: v1.55 Environment:
OS: Windows
JDK: 21
SpringBoot: 2.1.18.RELEASE
Steps to Reproduce:
Open a multi-module project in VSCode.
After the build is complete, unable to view all beans for the second module.
Expected Result: Expected to see all beans for the second module in the Spring Boot Tools extension.

Actual Result: The Spring Boot Tools extension only shows beans for the first module and fails to display beans for the second module. There are no error messages displayed in the UI, but the functionality is not working as expected.

Additional Information:
The issue does not occur in version v1.54, where beans for multiple modules are visible.
There might be a regression in the latest version that affects the display of beans in multi-module projects.

Error Message:
ERROR o.s.i.v.boot.app.SpringSymbolIndex - {}
java.lang.NullPointerException: Cannot invoke "org.eclipse.jdt.core.dom.Expression.resolveTypeBinding()" because the return value of "org.eclipse.jdt.core.dom.ReturnStatement.getExpression()" is null

Should be fixed with 349a395.

But it would be interesting to see under which exact circumstances this happens. It looks like the reconciler has issues with a specific return statement of a bean method. Would it be possible to share the project that causes the issue or the bean method definitions? Or to identify which bean method causes the problem and share only that specific piece with us?

Since the error appears to happen during reconciling, this error should happen every time you change the specific file, so maybe you can identify the specific file that way. That would be awesome.

I am unable to provide the entire project as it is my work project, but I can provide the file that is causing this issue.
Uploading TotInvoiceSettlementProgressServiceImpl.txt…

@Joshuahope Looks like the upload of that file didn't work out. Can you try again? That would be great!

I have extracted all the contents of the incorrect class into a separate test project, but the same problem still occurs. I can provide all the contents of this test project.

Thanks for attaching the sample project, but unfortunately it doesn't seem to reproduce the exception on my side...
