Reflections returns classes outside of configured package

[kevinm416]

Both of these attempts to search for Repository sub-types within the org.tamarack.models package returned classes outside of org.tamarack.models:

new Reflections(new ConfigurationBuilder().forPackages("com.tamarack.models"))
        .getSubTypesOf(Repository.class);

new Reflections("com.tamarack.models")
        .getSubTypesOf(Repository.class);

In particular, org.springframework.data.repository.PagingAndSortingRepository and org.springframework.data.repository.CrudRepository were returned in addition to the expected results. I would expect Reflections to only return classes in the package com.tamarack.models for both of those calls. Lmk if I'm using the library wrong!

I've the same issue when she package is part of another Jar file. I debugged into Reflections and noticed that in my case reason ist that the expansion of the URL of the package in the Jar discards the Package part and only keeps the jar-file part. So it scanned everything in the jar file.

I solved this by adding a filter to the configuration like that:

     Reflections reflections = new Reflections(
                new ConfigurationBuilder().forPackages(exampleClass.getPackageName())
                        .filterInputsBy(fn -> fn.contains(exampleClass.getPackageName()))
                );

Solved it for me.
