Description

When adding sources to the generated bundle and having module-info.java present, this file appears in the artifact's OPT-INF/src twice.

Technically, it seems that some entries are duplicated in a peculiar way. Running jar --list on the artifact produced from the sources listed below shows:

META-INF/
META-INF/MANIFEST.MF
META-INF/maven/
META-INF/maven/com.example/
META-INF/maven/com.example/com.example/
META-INF/maven/com.example/com.example/pom.properties
META-INF/maven/com.example/com.example/pom.xml
OSGI-OPT/
OSGI-OPT/src/
OSGI-OPT/src//
OSGI-OPT/src//module-info.java
OSGI-OPT/src/com/
OSGI-OPT/src/com/example/
OSGI-OPT/src/com/example/Main.java
OSGI-OPT/src/module-info.java
com/
com/example/
com/example/Main.class
module-info.class

Here is the small Hello World example that can be used to reproduce the behavior:
