TypeError raised when trying to propagate java Throwables using Thread.raise

[arielvalentin]

Here is an example script that reproduces the problem:

require 'java'

x = Thread.current
thread = Thread.new {
  begin
    Java::JavaLang::Class.for_name('not_real')
  rescue Java::JavaLang::ClassNotFoundException => e
    x.raise e #results in TypeError
  end
}
sleep 1

Example output:

→ ruby thread_raise_type_error.rb 
TypeError: exception object expected
                    raise at org/jruby/RubyThread.java:858
  chained_1_rescue_line_6 at thread_raise_type_error.rb:8
                   (root) at thread_raise_type_error.rb:6

This appears to be have been fixed at some point in the past. Seemingly on both 1.7.x and 9k:

Unhandled Java exception: java.lang.ClassNotFoundException: not_real
java.lang.ClassNotFoundException: not_real

Thanks @enebo!
