So who wants to run a 1.4 JDK? And what, exactly, prevents anything
from being compiled under 1.5? The only thing I can think of is the
user of the newly reserved word 'enum'. Big deal. How long has 1.5
been around now?
My perception is that there is only an ideological impediment to going
with 1.5. That is that it will be a long time before the
Stallman-approved JVMs support 1.5. So, the Java herd on Gentoo Stalls
the adoption of 1.5, just to "prove" that 1) you don't need it, and 2)
it's a very bad thing. Or at least it will be until the "free as in
slaves to ideology" crowd get their act together. Thanks for nothing.
