Remove woodstox-core-asl and stax2-api dependencies from Solr?
I could not find any dependencies on these libraries. Did I miss anything
or is it safe to remove them?

Did you track down which issues added them?

It should probably be proved that it doesn't affect perf to remove it
rather than the other way around.

Yeah; Uwe’s story is also as I understand it. IMO the dependencies aren’t
worth it unless someone demonstrably proves otherwise. Given that SolJ
mostly uses javabin (response by default but not request; and requests tend
to be small), XML performance is less of an issue as well.

Hi,
There is not a direct dependency. The STAX-parser shipped with the JDK is too slow (said by some people). I am not sure if this is still true with Java 7 and Java 8, but In Java 6 it was! When having Woodstock in classpath, it plugs this XML parser into the JDK with SPI (like our lucene codecs). Solr should work without woodstox, but you may have slower XML imports (StAX is used by UpdateHandler#XMLLoader only).
