I seem to have stumbled onto a problem with some handles and >10 or
>11 arguments.
For this code:
System.out.println(target.type());
System.out.println(breakJump.type());
target = MethodHandles.catchException(target,
JumpException.BreakJump.class, breakJump);
This pair of method types works:
(org.jruby.runtime.callsite.CacheEntry,org.jruby.runtime.ThreadContext,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,java.lang.String,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.Block)org.jruby.runtime.builtin.IRubyObject
(org.jruby.exceptions.JumpException$BreakJump,org.jruby.runtime.callsite.CacheEntry,org.jruby.runtime.ThreadContext,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,java.lang.String,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.Block)org.jruby.runtime.builtin.IRubyObject
But this pair produces an error:
(org.jruby.runtime.callsite.CacheEntry,org.jruby.runtime.ThreadContext,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,java.lang.String,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.Block)org.jruby.runtime.builtin.IRubyObject
(org.jruby.exceptions.JumpException$BreakJump,org.jruby.runtime.callsite.CacheEntry,org.jruby.runtime.ThreadContext,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,java.lang.String,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.builtin.IRubyObject,org.jruby.runtime.Block)org.jruby.runtime.builtin.IRubyObject
Here's the error:
Caused by: java.lang.IllegalArgumentException: no restarg in

Looks like a bug...I have not had a chance to dig into it.
