Mamta A. Satoor commented on DERBY-4304:
----------------------------------------

With revision, committed 798742, made changes so that during server shutdown sub-steps, we
print the exception info and then move on to the next step in server shutdown.The commit comments
were as follows
*****************
During server shutdown substeps, catch any exception thrown, print it to console along with
stack trace and then move on to the next substep rather than re-throwing the exception after
console printing.

> While working on DERBY-4053, found that an exception from Connection.close was not handled
properly by the server shutdown code which caused a new instance server startup to hang. Resolved
the problem with Connection close but in general, we should
> 1) Make sure an exception during shutdown processing does not prevent the remaining shutdown
tasks, like closing the server socket from occurring. 
> 2) Make sure any exceptions that occur in shutdown processing are reported to the console.
