Description
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.)
