Description
Two DNS testcases fail with JDK 5.0u13 b01 and pass with 5.0u12fcs, look like regression introduced in 5.0u13 b01. The tests fail at all platforms. 

The following tests fail:

# ListTests/index.html#ListInteriorCached: index_ListInteriorCached
# NameClassPairTests/index.html#GetNameInNamespace: index_GetNameInNamespace

Both with java.lang.NullPointerException. but pass with prev update.

= How to reproduce:
 
1. log on to jqa-sf1.ireland as root (pasw in comments)

2. set JAVA_HOME 

export JAVA_HOME=/export/home/JDKS/jdk1.5.0_13 

3. execute script 

/net/jqa.ireland/jqa6/dtf/dtf_ws/suites/150_JNDI_RMI/run_jndi_stand_alone.sh $JAVA_HOME "-client -Xint" DNS

4. find results in /export/home/JQA/ts150/jndi/SunOS_5.11_x86/DNS

Comments
EVALUATION According to PDE the two best choices for implementation are the following: (we are contacting the cu, Ericsson, to see which they prefer) 1) The (Dns) Context controls closing of itself. It keeps track of all enumerations obtained from it. If an enumeration over the context is done, that's marked as done by the context and the context is not closed unless its close() method is explicitly called. The context is not closed even if context.close() is called by the application when one of the enumeration is still being used. This allows any number of enumerations to be launched over the context and results in safe closing of the context. This required explicit calling context.close() for closing the connection. or the current situation: (if the cu is happy with the fix we made then all we have to do is update the testcase in this case) 2) The enumeration (once done) closes the context automatically, even if the application does not explicitly call context.close(). For performing any new operation, a new context needs to be obtained. This would let the applications handle close() for them automatically. However, it won't allow more than one enumeration to be obtained from the given context. This is the current implementation of DNS Provider. Obviously option 2) would be preferable as it is a simple enough change to the testcase but we will wait on a customer response.

EVALUATION regression caused through fix for 5053708. dnsClient causes NPE through it being set to null on Resolver.close() method.
