This is the behavior that I'm accustomed to:
$ java test
Exception in thread "main" java.lang.Error: getenv no longer supported, use properties and -D instead: HOME
I ran this test using "Java(TM) 2 Runtime Environment, Standard
Edition (build 1.4.2_12-b03)", and recall similar disfunctional
behavior with older JREs.

Yup, "Java(TM) 2 Runtime Environment, Standard Edition (build
1.5.0_07-b03)" now works as expected. Thanks for the update, Patrick.
If I can't weasel some native library version checks into JavaHL's
Java code, we'll go with this as a best-effort attempt to maintain
some compatibility with older native library versions.
Since it's only me that'll be embarrassed here, I'm going to CC the
dev list on this conversation. Hope ya don't mind.
