However, in a dynamic environment like an application server, and especially JBoss with its support for hot deployment are that class cast exceptions, linkage errors and illegal access errors can show up in ways not seen in more static class loading contexts.

However, scanning all JARs on the classpath could be very time-consuming if you have large applications with many JARs deployed.

The aim of this release is to provide fixes for bugs reported by the community against previous JBossAS v4.
