Modifier and Type	Field	Description
private final Map<String,sun.misc.SignalHandler>	fakeOriginal
private static final sun.misc.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<sun.misc.Signal,sun.misc.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.

Field Details

original

private final Map<sun.misc.Signal,sun.misc.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.

fakeOriginal

private final Map<String,sun.misc.SignalHandler> fakeOriginal

IGNORE

private static final sun.misc.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). See https://github.com/jruby/jruby/pull/6584
