I've incidentally been working on this lately.
The results of my efforts are here: https://github.com/sqreen/nashorn
The tests that don't require external js libraries all pass, with some
exceptions:
* I couldn't get the tests requiring jemmy to pass. IIRC, the original
ant files pointed to some urls of jars that don't exist anymore and I
couldn't find the exact jemmy and jemmyjfx versions expected.
* Half a dozen sandboxing tests don't pass because they require that
nashorn be loaded on the platform classloader. More precisly, when
running with a security manager and
with -Djava.security.properties= pointing to a file restricting class
loading with package.access, it seems to rely on the fact that the
platform classloader doesn't have the call
to SecurityManager::checkPackageAccess that the app classloader has
I haven't worked on the benchmarks.
Most of the work was moving to gradle. I didn't have to make a lot of
changes to the codebase. I had to change to the Unsafe in sun.misc
rather than the internal one, to change the parent module layer for the
scripting JPMS module created at runtime for when nashorn isn't loaded
on the boot layer, then some tests required small tweaks but I don't
remember much else.
I also copied the asm library to avoid having to --add-exports the
internal one, but maybe this can be changed to the mainline asm library.
As to the jjs executable, that was not a problem, and some tests require
it anyway, which is why I worked on it. The only difficult was that when
built separately from openjdk, the -J-XXX option is not available, but
this can be worked around with the JDK_JAVA_OPTIONS environment variable.
