> Update ASM dependency to 5.0.4
> ------------------------------

> Key: TIKA-1705

> Issue Type: Task

>
> Currently the Class file parser uses ASM 4.1. This older version cannot read
> Java 8 / Java 9 class files (fails with Exception).
> The upgrade to ASM 5.0.4 is very simple, just Maven dependency change. The
> code change is only to update the visitor version, so it gets new Java 8
> features like lambdas reported, but this is not really required, but should
> be done for full support.
> FYI, in LUCENE-6729 we want to upgrade the Lucene Expressions module to ASM
> 5, too.
> You can hot-swap ASM 4.1 with ASM 5.0.4 without recompilation (so we have no
> problem with Lucene using a newer version). Since ASM 4.x the updates are
> more easy (no visitor interfaces anymore, instead abstract classes), so it
> does not break if you just replace the JAR file. So just see this as a
> recommendatation, not urgent! Solr/Lucene will also work without this patch
> (it just replaces the shipped ASM by newer version in our packaging).
