I think I figured this out ... here is what I think happened. The base version
of java that is downloaded with Jenkins is a 32 bit version of java. When you
go to the manage jenkins --> configuration --> install JDKs, when you select
from the list it will pull down the 32 bit version for windows. Once I
converted Jenkins to run under a 64 bit JDK, the JDK versions pulled down are
64 bit versions. My ANT code was running under the JDK that was configured on
the job page, which turned out to be a 32 bit version.
I guess Jenkins is downloaded and installed with a 32 bit version in the
windows native package to support a lowest common denominator. This should be
noted as a caveat for the native package on windows.

I just set up a new instance on jenkins and had it pull down an ANT
installation ant 1.9.4. I pulled a job from my old jenkins server and ran it.
It invokes ANT to compile a bunch of java code. The build fails with an
out-of-memory. I started jenkins to run under a 64bit JDK. The java opts on the
jenkins start up in jenkins.xml are:
-Xrs -Xmx4096m -XX:MaxPermSize=256m
-Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar
"%BASE%\jenkins.war" --httpPort=8080
I'm not sure if I have to pass ANT via ANT_OPTs a memory setting, but I did set
the environment variable ANT_OPTS to -Xmx2048m. I do not see this set on the
older server. I set the ANT_OPTS to 4096 and it returned that the specified
size exceeds the max representable size.
Not sure why I'm getting an out-of-memory on the new installation. The code
ruins find on the older server. Any thoughts?
