[jira] [Commented] (XBEAN-230) Update to ASM 4

    [ https://issues.apache.org/jira/browse/XBEAN-230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13667013#comment-13667013 ] 

Mark Struberg commented on XBEAN-230:
-------------------------------------

We will create a new package asm4 which also will get shaded into a new package. This way we can effectively prevent classpath clashes when some tools (e.g. openjpa) like to use asm-3 stuff and others (e.g. openwebbeans) like to use asm-4. 

The downside is that your code needs to upgrade to the asm4 package when moving. But I think this will be a minor point in comparison to the stability we gain from that move.

> Current upstream version of ASM is 4.1, XBean 3.12 uses ASM 3.2.
> ASM 4 fixes many bugs and adds many features (including full Java 7 support). It would be beneficial for XBean to use ASM 4.
> Unfortunately ASM 3 and ASM 4 APIs are incompatible and XBean would need some work to migrate to ASM 4. (ASM upstream promises no more incompatible changes.)
