Weird irb behavior osx

Just wanted to point this out.
Don’t know if anyone else is experiencing this.
occasionally, I will accidentally hit control C to escape out of irb
When doing this in 1.9 the next command I type returns ^C
Seems odd…
Any idea why this happens this way?

slog:~/ruby19/bin UniX$ /Users/UniX/ruby19/bin/irb
irb(main):001:0> RUBY_VERSION
=> “1.9.0”
irb(main):002:0> require ‘java’
irb(main):002:0> ^C
irb(main):002:0> wtf?
