The data I'm harvesting is the strings in .properties files, for which Java has
built-in functionality to read and decode. I would rather not write my own Java
property file parser in RB.

Good point. Of course if I could get standard output to work then I wouldn't
need a socket at all.

dim sh as new LoaderShell(ostr)
sh.Mode = 1
sh.Execute("java -jar " + jar.ShellPath + " " + dir1.ShellPath + " " +
dir2.ShellPath)
I know the parameters are right because if I run it synchronously (mode = 0)
the Result property has the Java output. But the output can be sizeable so I
would rather not buffer all of it into this property before I can do some work
with it.
