I'm still only half paying attention, but I agree with Alexander that
the low-level infrastructure in libjimage is fishy. The rule should be
that file descriptors created by the JDK should have the CLOEXEC bit on.
But even if the CLOEXEC bit was forgotten, the subprocess code should
still succeed in closing that fd and use FAIL_FILENO for the error
reporting pipe in childproc.c.
That's two independent problems and I suggest adressing them one at a time.
I anyone willing to get my patch applied? I do not have commiter rights
yet, but my OCA is already processed.
