[Building Sakai] java 6

[Charles Hedrick]

We're doing the last 2 weeks of testing for Sakai 2.6 under Java 6.  
We're still building under Java 5. The only configuration change is  
adding -Dsun.lang.ClassLoader.allowArraySyntax=true. If we don't run  
into problems during testing, I'm considering running under Java 6 in  
production. I also have a system running Sakai 2.5 under Java 6,  
though we won't use it in production unless we have an emergency  
during the next 2 weeks.
