In fact, it looks like the resources object here is of type InputStreamEnumeration (in com/sun/naming/internal/VersionHelper12.java), with an open-on-nextElement style. This means we can completely remove the while (resources.hasMore()) block.

Lance and Andrew added for confirmation.

Thanks Max

A small webrev:

http://cr.openjdk.java.net/~weijun/8003263/webrev.00/ The reason is that 8003120 added a new line InputStream istream = (InputStream)resources.next(); but resources is already of type NamingEnumeration. Building now shows ../../../src/share/classes/com/sun/naming/internal/ResourceManager.java:563: warning: [cast] redundant cast to InputStream InputStream istream = (InputStream)resources.next(); Noreg-trivial. Looks okay to me, just wondering if we should do a more complete fix for 8003120 while you are there (meaning it should attempt to close all resources even if there is an IOException is thrown during close). -Alan
