`.class` file not mapped if .java also exists on deploy side

Input: MPAndroidChart-v2.2.4
URL:
Devel: https://github.com/PhilJay/MPAndroidChart/archive/refs/tags/v2.2.4.zip
Deploy: https://github.com/PhilJay/MPAndroidChart/releases/download/v2.2.4/mpandroidchartlibrary-2-2-4.jar

I ran the map_deploy_to_develop:Java pipeline in SCIO, but some .class files found in deploy side returned as they don't have match in the devel which is in correct.

I suspect the issue is the deploy side contains both .java and .class files, and the .java file maps to the corresponding .java file on the devel side, which results in the .class file on the deploy side being left unmapped.
