7056489: test/com/sun/jndi/ldap/ReadTimeoutTest.java loops or times out

[Alan Bateman]

I need a reviewer for a small fix to a test that I caught looping on my 
system. The test creates a server thread that emulates a non responding 
LDAP server. Unfortunately the thread goes into a loop reading from the 
connection once it is closed. I'll bet the original author only tested 
this on Solaris where it would have completed as intended due to 
now-disabled and legacy interruptible I/O support. While I was there I 
eliminated the hard coded port that would cause it to fail if that port 
were already in use. The test could be improved in other ways too but 
for now the webrev with the proposed changes is here:

Thanks,
