It looks like we are very close to having the Scala repl working; perhaps one native method away:

[ERROR] Failed to construct terminal; falling back to unsupportedjava.lang.IllegalArgumentException: Invalid terminal type: jline.UnsupportedTerminal

Documentation:

Block current thread, returning when a balancing unpark occurs, or a balancing unpark has already occurred, or the thread is interrupted, or, if not absolute and time is not zero, the given time nanoseconds have elapsed, or if absolute, the given deadline in milliseconds since Epoch has passed, or spuriously (i.e., returning for no "reason"). Note: This operation is in the Unsafe class only because unpark is, so it would be strange to place it elsewhere.

public native void park(boolean isAbsolute, long time);

Corresponding unpark documentation:

Unblock the given thread blocked on park, or, if it is not blocked, cause the subsequent call to park not to block. Note: this operation is "unsafe" solely because the caller must somehow ensure that the thread has not been destroyed. Nothing special is usually required to ensure this when called from Java (in which there will ordinarily be a live reference to the thread) but this is not nearly-automatically so when calling from native code.

Parameters:
thread the thread to unpark.

public native void unpark(Object thread);

It doesn't seem to respond to input properly, and running it with scripts as an argument yields ClassNotFoundException messages.

Expected behavior:

$  scala HelloWorld.sc
Hello, world!

So there's still work to be done!

The JLine error is expected, see ab79a98. Scala should probably handle it better, but that's not really our fault.

Yeah, but input doesn't seem to get evaluated at all.

The REPL is so close to working!

That entry seems to have slain the compiler.  Shall I replay
your session? I can re-run each line except the last one.
[y/n]

I believe the below issue is caused solely by #159, which separates bootstrap-loaded classes from the application-loaded classes. Normally, all of the Scala JAR files are on the bootstrap classpath, which our command line parser doesn't support (it has weird syntax).

Tried the newest version of Scala in the new-objects branch; looks like the futures timeout has been increased:

Hmm, now I can't reproduce the earlier failure. Interesting. Well, I guess Scala works (slowly) in new-objects!
