Path added with `addClassPath` ignored by `init(opts)` method

[nicolaspayette]

I tried to do something like this:

JavaCall.addClassPath("/mypath/*")
JavaCall.init(["-Xmx512M"])

It took me a while to understand why my class path was ignored.

You need to do either:

JavaCall.init(["-Xmx512M", "-Djava.class.path=/mypath/*"])

or:

JavaCall.addClassPath("/mypath/*")
JavaCall.addOpts("-Xmx512M")
JavaCall.init()

It would be nice if init(opts) honored paths added via addClassPath (though this raises the question of what to do if the user also includes "-Djava.class.path=..." in opts). Short of that, maybe the docs could mention the possible gotcha.

As of 141df7d (should be in v0.7.4) the behavior is now as follows:

julia> using JavaCall

julia> JavaCall.addClassPath("foo")

julia> JavaCall.init(["-Xmx512M","-Djava.class.path=bar"])

julia> JavaCall.getClassPath()
"foo:bar"
