Interrupt ignores exception message #4286
Description
Environment
jruby 9.1.6.0 (2.3.1) 2016-11-09 0150a76 OpenJDK 64-Bit Server VM 25.72-b15 on 1.8.0_72-b15 +jit [OpenBSD-x86_64]
Expected Behavior
With code:
$ jruby -e 'begin; raise Interrupt, "foo"; rescue Exception; puts $!.message; end'
I expect output will be foo, as that is MRI's behavior and the behavior of earlier JRuby versions. Example with ruby 2.3:
$ ruby23 -e 'begin; raise Interrupt, "foo"; rescue Exception; puts $!.message; end'
foo
Actual Behavior
$ jruby -e 'begin; raise Interrupt, "foo"; rescue Exception; puts $!.message; end'
Interrupt
While I'm understandably not relying on this behavior in production, it did break Sequel's tests. I believe this behavior changed between 9.1.5.0 and 9.1.6.0.
