LUCENE-4582: Better detection of incompatible Java version for forbidden-apis
checker. Later updates of ASM will support Java 8, but when Java 9 comes out
with again a new class file format, we can handle this.
> Fobidden API checker does not work with recent JDK 8 builds

> Key: LUCENE-4582
> URL: https://issues.apache.org/jira/browse/LUCENE-4582
> Project: Lucene - Core
> Issue Type: Bug
> Components: general/build
> Affects Versions: 4.0, 4.1, 5.0
> Environment: JDK 8 build 65
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Attachments: LUCENE-4582-workaround.patch,
> LUCENE-4582-workaround.patch

>
> The forbidden API checker currently uses ASM 4.0 to do checks for calls to
> APIs, the Lucene developers don't like (those with default charsets).
> The Lucene classes are of course compiled with old (JDK 1.6) class file
> format, but the checker has to load also classes from rt.jar, shipped with
> the JDK. Unfortunately JDK 8 build 65 changed the class format (new version
> is 52.0), so the checker fails with an IllegalArgumentException while loading
> platform classes; see [their bug
> tracker|http://forge.ow2.org/tracker/index.php?func=detail&aid=316375&group_id=23&atid=350023].
> The bug is not yet fixed in ASM 4.0 or 4.1, so I will disable the forbidden
> API checker in JDK 8 (until an update is released). I will keep this issue
> open until this is solved.
> I will also commit an update to version 4.1 of ASM.
