This patch will need security review as it leaks sensitive information 
into exception messages. It may be that it needs to predicated on a 
security property.

If this proposal goes ahead then the implementation needs cleanup. The 
upcall from the JNU_* function to jdk.internal.util is a messy I think 
we need to look at alternative to avoid this. Also the patch needs to be 
re-formatted to get it consistent with the existing code (e.g. overly 
long 150 character lines need to be trimmed down to be consistent with 
the existing code for example).
