earth% cat /var/db/pkg/apache-ant-1.7.0_1/+REQUIRED_BY
cat: /var/db/pkg/apache-ant-1.7.0_1/+REQUIRED_BY: No such file or directory

Given that I do not feel I can afford to have Java on the system, this
is a sacrifice I feel is necessary.  In the process of updating ports,
apache-ant has already been reinstalled.  I had installed kaffe when I
removed jdk*; but apache-ant now seems to depend on diablo-jdk.

earth% pkg_info -r diablo-jdk-
Information for diablo-jdk-

Depends on:
Dependency: xtrans-1.0.4
Dependency: xproto-7.0.10_1
Dependency: xextproto-7.0.2
Dependency: javavmwrapper-2.3

earth% cat /var/db/pkg/diablo-jdk-

At least I do not yet see java_vm (which seems to have been the culprit
in cases where I was able to get back into the system) yet reappearing.

When I encountered difficulty this morning, I had left both firefox and
an ports upgrade running.  In the past, I had associated the problem with
a java script from Blackboard at the university where I attend and teach,
but in the situation this morning, I had not invoked that script.

So I'm guessing that java_vm had been invoked by apache-ant which previously
depended on jdk* rather than diablo-jdk*.

I am wondering if I have any reason to believe that diablo-jdk is
sufficiently different from jdk to avoid the problem.
