Lukasz Gajowy commented on BEAM-5495:
-------------------------------------
I did not consider xbean nor knew about it. Since classgraph looked the most
promising from what I saw, does the job well and can be easily replaced with
other libraries if needed (thanks to the way the whole PR was implemented) I
decided to use it.

> Key: BEAM-5495
> URL: https://issues.apache.org/jira/browse/BEAM-5495
> Project: Beam
> Issue Type: Bug
> Components: runner-flink, runner-spark, sdk-java-core
> Reporter: Romain Manni-Bucau
> Assignee: Lukasz Gajowy
> Priority: Major
> Fix For: 2.19.0
>
> Time Spent: 14.5h
> Remaining Estimate: 0h
>
> Issue are:
> 1. it assumes the classloader is an URLClassLoader (not always true and java
> >= 9 breaks that as well for the app loader)
> 2. it uses loader.getURLs() which leads to including the JRE itself in the
> staged file
> Looks like this detect resource algorithm can't work and should be replaced
> by a SPI rather than a built-in and not extensible algorithm. Another valid
> alternative is to just drop that "guess" logic and force the user to set
> staged files.
