No,
it is because javadoc calls System.exit(). Itmay be possible to use a loader
and a security manager to avoid that but I don't know if it is worth the
effort.

Cool. That sounds like a little tool that I've been wanting to write for a
while (the jar merge functionality expressely). Now that I know what JLink
is I'll be looking forward to seeing it in Ant.

Yes, I've been hacking a little bit to make ant run smoothly in
JShell. I'm planning on including a build of ant in the next release
of JShell. For now, here's a URL where you can download ant.jxe:

Yes, I wrote jlink expressly for this purpose, out of frustration
with the jar tool. It can merge multiple directories (starting from
top level of each directory given), .jar files, and individual files
(at top-level of resulting output file) into a single output .jar
file. Here's the usage text:
usage: jlink output input1 ... inputN
All of the sources to JShell are browsable online starting here:
http://www.gjt.org/servlets/JCVSlet/list/gjt/org/jxe
jlink sources are here:

JShell, ant and jlink
Posted by Matthew Kuperus Heun <ma...@gaerospace.com>.
Patrick:
It appears that I'm travelling down some paths that you've already
tread. I just signed up on ant-dev and was pleased to find you
there. JShell is looking more and more attractive, and I'm
considering moving over to using it, chiefly because of the tools
that can be run there. I have a few questions.
(1) Have you successfully been using ant in JShell? Are there some
pointers that you could give me for setting that up? (No ant command
is included in the distribution of JShell that I have.)
(2) I'm looking for a tool that will merge the contents of a
"library" jar file with .class files that I want to put into a jar.
Will jlink do this? Where can I find some details on jlink?
Cheers,
Matt

JShell disallows that by using a custom version of the System class
that it provides via class loader. Ant could probably use the same
approach.
