This is a parent issue to track the work for requiring Java 1.6 in Sakai 2.9.
From the list:
2.8: recommend 1.6 - code compiles in 1.5
2.9: require 1.6 - no guarantee that code will compile/run in 1.5
If we want to drop 1.5 then we need to make sure that the
code compiles after adjusting Maven's compiler plugin
settings from 1.5 to 1.6. Last time I checked (early
December) the kernel failed to build due to an issue with
kernel util's validater.java due to "unmappable character
for encoding UTF-8 (53 cases)."
Yep lets get any required modifications committed into trunk, and enforce 1.6 as soon as possible so we can iron anything out early.
Let's make this a 2.9 blocker and work on this at least as soon as 2.8.0 is released.
