The spring-core module currently does not specify a version for the import of the org.objectweb.asm* packages. Since asm v1 is binary incompatible with v2 this can cause a problem. Some other projects (e.g. hibernate) require the v1 version while Spring requires the v2 version.

The pom.xml should thus be updated, something like:

   org.objectweb.asm*;resolution:=optional;version=2.2.3,

The patch is:
