Can plugin handle multiple top-level classes in java?

[Arthurm1]

I'm using the semanticdb java plugin to recompile the java.net.URL class in Java 17. Source code here

I get the semanticdb information attached below.

There doesn't appear to be any semanticdb info between lines 176 and 1712, so (in Metals) I can't get definitions on the code in that range.
One example is URLConnection on this line has no info.
There are a number of private variables that also don't have definitions.

This file is slightly unusual for java as there are 2 top-level classes defined. Only one of them public. The non-public one does have semanticdb.

Am I reading the semanticdb info wrong, or expecting too much from it or is the plugin foxed by multiple classes or something else?

I'm using version 0.7.4 of the plugin
