I just finished an Advanced Jboss training class last week, and during a disccussion on classloaders, the following idea occurred to me.
When the classloader encounters a Java class which has already been loaded, it just ignores it. This can cause problems when there is more than one version of a class among diferent archives.
Why not have
- a warning, optional if neccessary, that would warn the developer that the same class occurred in multiple archives
- a warning if the duplicate class is not indentical to the previously encountered occurence
