The JNDI close call is not implemented inside the application server.
I'm running Application Server Platform Edition 9.0_01 (build b02-p01) on
Windows XP with 1.5.0_11-b03.
Look at appserv-core/src/java/com/sun/enterprise/naming/NamingManagerImpl.java,
line 1496, and it explicitly states that close() is not implemented. This is
part of the NamePairsEnum class and is called as a javax.naming.Context
This was called from
(JNDIConfiguration.java:175), part of the Apache Jakarta Commons Configuration
