Running java with CompileTheWorld option fails on ARM, PPC and x86 when compiling sun/nio/ch/SocketChannelImpl.
The problem is not reproducible on 6u21 baseline.

SocketChannelImp::connect() is the method crashing during compilation.
from_opr->type() is T_ADDRESS
to_interval->type() is T_INT
mainline 6u23 crashes at the same spot, therefore not Embedded SE specific.
Redispatched.
