NullPointerException during Java Search

[ptziegler]

This happens both in the 2024-12 and the 2024-09, but likely also in older versions of the Eclipse IDE.

(Plain stack trace for readability)

This is the reference causing the exception:

I believe that this issue is caused by the Nullable annotations of the Checker Framework used by Guava. The packages are not specified in the bundle manifest, it is not included in the target platform/Eclipse installation and therefore not in the classpath.
