Eclipse seems to be unable to find a type in the same JDK

I am not sure how to reproduce this. Please have a look at the screenshot and the error message reported there.

Is this a broken index or is something else corrupt within the JDK?

Eclipse IDE for Java Developers (includes Incubating components)

Version: 2024-03 (4.31.0)
Build id: 20240307-1437

I would assume .claspath is mis-configured. Probably side effect of #2421 where some libraries manage to contain "duplicates" of java.* packages.

I thought of this too. However, this is a different project and classpaths are not connected. Also, it does not have org.osgi.foundation jar.

I managed to make the error go away using the following steps:

• Right click project, select Build Path > Configure Build Path ...
• Switch JRE Library to execution environment Java SE-17 (which is a different JDK in my case)
  -> at this point the problem went away
• Switch JRE Library back to alternate JDK and the one that was originally used
  -> at this point the problem did not come back

Thus, it must have been some internal state messed up. 🤷

It will probably happen again after some time.

probably duplicate of #2877
