As it happens, there was a bug in that code (6526376) that caused NPE
to be thrown so jdk7 b10 is the first build where
IllegalStateException is possible.
Ah I see. Seems to me that 6526376 took the easy fix and ignored the
underlying issue of whether this should be an exceptional circumstance
or not. :(
or probably earlier in 4809375 when there was code introduced to
explicitly handle this case.
:
I think there's probably a way to keep the list in java code (for
resource management) and also add the fd to list used by the VM.
Adding a new "VM shutdown hook" to be executed by the VMThread at the
termination safepoint would probably be the best place to deal with this.
That would work but does mean another dependency in the VM code.
I'll create a bug with a link to this discussion so that this issue
doesn't get forgotten.
