Nested and Inner Type Summary

Modifier and TypeClass and Description
private static class
SunSignalFacade.JRubySignalHandler

Field Summary

Modifier and TypeField and Description
private final Map<String, SignalHandler>
fakeOriginal

private static final SignalHandler
IGNORE

This is used instead of SignalHandler.SIG_IGN as Signal.handle(sig, anyHandler) seems to no longer work after Signal.handle(sig, SIG_IGN).

private final Map<Signal, SignalHandler>
original

Remembers the original signal handlers before JRuby started messing around with them, to emulate Signal.trap(...,"DEFAULT") that's supposed to restore the platform default handler.
