JAXP contains a number of calls to dprint, which are never printed unless the jaxp.debug flag is set.

A number of the strings created to call dprint are quite expensive to calculate. For the appserver, it is *very* expensive to calculate toString from the classloader, which contains many, many jar files. So in particular, the dPrint calls that use the classloader:

 dPrint("found jar resource=" + serviceId + " using ClassLoader: " + cl);
dPrint("created new instance of " + providerClass + " using ClassLoader: " + cl)

have a significant impact on our performance.

All these calls should create strings only if the debug flag is set, rather than always creating the strings.
