java 1.4 versus 1.5

[Owen O'Malley]

Java 1.5 has been out for a couple of years now and has some nice 
improvements in the libraries. In particular, I wish I had access to 
the timeout settings on UrlConnections. Would anyone object if starting 
with the 0.3 release this week, we required java 1.5 to compile and run 
Hadoop?
