jdk1.4.2 & Inet4Address resolver thread-safety

I've been tracking down and fixing a few bugs we've witnessed in  
production.

The first involves a lack of thread-safety in j2se/src/solaris/native/ 
java/net/Inet4AddressImpl.c due to the use of gethostbyname()/ 
gethostbyaddr() on BSD systems:

     An unexpected exception has been detected in native code outside  
the VM.
     Unexpected Signal : 11 occurred at PC=0x481328DB
     Function=strcasecmp+0x33
     Library=/lib/libc.so.5

     Current Java thread:
             at java.net.Inet4AddressImpl.getLocalHostName(Native  
Method)
             at java.net.InetAddress.getLocalHost(InetAddress.java:1178)
             at javax.mail.internet.InternetAddress.getLocalAddress 
(InternetAddress.java:477)

I have further details and a patch to fix the issue. In light of the  
Java license requirements, is this the correct forum for such  
discussion?

Thanks,
Landon Fuller
