Oh Eric, Eric, Eric... Java is not that hard. At least compared to
something like the TOS build "system". It even {used to be} a rather
rationalized and simple alternative to most egregious C++ shenanigans.
But anyway... There was one more question in the complaint list:

Add '.' to your CLASSPATH... See if you can find a place where
CLASSPATH is actually set, in files like .bahsrc or .profile,
and add the dot to the list using a semi-colon ';' as a separator.
Or else do this:
export CLASSPATH="$CLASSPATH;."
I explicitly set PATH and CLASSPATH in my .bashrc so I know what
I'm getting and {think that} I have some control over my world...
And any Java above and beyond 1.4 is fine for TOS, at least until
Oracle destroys the backward compatibility feature. I forget exactly
what went in at 1.4, maybe generics, but some TOS code won't compile
with previous versions. "Someone" "should" fix tos-check-env, no?
