Patch to compile ASM 2.2.3 against Java 1.4
SerialVersionUIDAdder throws an UnsupportedOperationException at line 434. It
passes the cause via a constructor, but that wasn't added until Java 1.5. It's
therefore breaking in my 1.4 build system.
I've attached a simple patch to pass the cause via a setter, which works in 1.4+.
