[evla-sw-discuss] Java 7 on EVLA

[Bryan Butler]

not quite sure what you mean by "the EVLA will be switching to Java 7 
soon," kevin?

we've talked about some applications moving to it, but had no (formal) 
discussion of mandating that all of them have to...

While Java for the Mac OS X is moving away from Apple and to Oracle control, it is still not ready for prime time and OS X software updates still use Apple versions that do not include Java 7 (as far as I know).

There are a significant number of Macs used (or perhaps better to say a number of significant people using Macs) in the development and testing of the EVLA now (at least on WIDAR); compiling client applications under Java 7 would alienate them.

We will start testing Java 7 on CMIBs next week.
