the javaagent-all.jar file contains duplicate files

[tobias-]

Describe the bug
There are multiple files with the exact same name in the opentelemetry-javaagent-*-all.jar file. This doesn't seem to have any negative effect other than enlarging the jar file distributable. None of the class files seems to have different size nor crc.

Steps to reproduce

Run the following to get a count and a list of the files.

unzip -v otel-all.jar | cut -c59- | sort | uniq -d

What did you expect to see?
Empty result because every file should only be included once.

What did you see instead?
389 duplicate files, ie files that are added to the jar twice.

What version are you using?
1.3.1

Environment
Not relevant
