Hi all!

I saw this was fixed for subtraction and division earlier: #1648, #1633, #1442, #1441

The exception is not caught by a rescue Exception and breaks our app.

This should probably be covered by a RubySpec?

With MRI 2.1.3:

reserve-pc:TelenorGS uwe$ irb
2.1.3 :001 > require 'bigdecimal'
 => true 
2.1.3 :003 > BigDecimal('1.23') * nil
TypeError: nil can't be coerced into BigDecimal
    from (irb):3:in `*'
    from (irb):3
    from /Users/uwe/.rvm/rubies/ruby-2.1.3/bin/irb:11:in `<main>'

With JRuby 1.7.16:

reserve-pc:TelenorGS uwe$ irb
jruby-1.7.16 :001 > require 'bigdecimal'
 => true 
jruby-1.7.16 :003 > BigDecimal('1.23')
 => #<BigDecimal:5b275dab,'0.123E1',3(4)> 
jruby-1.7.16 :004 > BigDecimal('1.23') * nil

Sorry, one mistake: The exception _CAN_ be caught by a rescue.

Did you test this on master or 1.7? Because now 1.7 works and master fails :-)

It's possible that there are specs for this in the specs for rubysl-bigdecimal. The specs for all the rubysl gems no longer live in RubySpec...we need to stitch them together from the gem repos, I guess.

Fixed and test added to MRI's suite. We'll update tests more frequently.

@headius this issue should be reopened. In this case, the exception type should be TypeError.

on current master(336e527)
