Are there any magic options to say "load a jar - just once ... not once for each thread", or to tell Java to load from the shared classes cache? It feels like an old (non java) problem of having a non reentrant load module, so it was loaded from disk every time, instead of reusing the in-memory copy.
I doubt that Java is loading the classes multiple times. I think the class cache is more for sharing between different instances of the JVM.
I suspect that there is something else in the jar that is being accessed that is not cached. I see that jar contains a number of properties files e.g.
/com/ibm/eserver/zos/racf/nls/IRRExceptionMessages.properties I wonder whether they could be what is being repeatedly loaded?
