So far so good.

My guess is that when updating ports some Java application is also
being installed which requires build from source and as a result
installs ant.  It'd be good to check the installed applications for a
Java one.

Obvious.

No clue here.  But I guess it's not about java_vm that your system goes
blank since I'm working/developing with both diablo-jdk-1.5.0_06 and
jdk-1.6.0_01 on an average machine running 6.2-p7.

I'm not sure but I paste my javavm_wrapper configuration.  It might be
useful:
# JDK 1.6
#JAVA_HOME=/usr/local/jdk1.6.0
#JAVA_OS=native
#JAVA_VENDOR=freebsd
#JAVA_VERSION=1.6
#JAVAVM_OPTS=-XX:+UseThreadPriorities

# JDK 1.5
JAVA_HOME=/usr/local/dialblo-jdk1.5.0
JAVA_OS=native
JAVA_VENDOR=freebsd
JAVA_VERSION=1.5
JAVAVM_OPTS=-XX:+UseThreadPriorities
