Hi Greg,
that for the confirmation. Looks like a showstopper for a developer like
me. Even my webapps won't run because they rely on ProcessBuilder.
Is there anything I can help to get this fixed? That type of C code is,
unfortunately, out of my knowledge.
I want to verify your (and others) great work against all Maven
subprojects as well as CodeHaus to find subtile bugsin the port.
