JRuby's instance_exec only accepts up to 3 arguments
----------------------------------------------------
Key: JRUBY-3594
URL: http://jira.codehaus.org/browse/JRUBY-3594
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.2
Reporter: Charles Oliver Nutter
Assignee: Thomas E Enebo
Priority: Critical
Fix For: JRuby 1.3
This breaks some specs the rspec guys are running, but shouldn't affect most
specs (since matchers almost never have more than three arguments:
http://gist.github.com/99209
The problem is that our instance_exec is specified as follows, forcing it to
have no more than 3 arguments:
{noformat}
@JRubyMethod(name = "instance_exec", optional = 3, rest = true, frame =
true)
public IRubyObject instance_exec(ThreadContext context, IRubyObject[] args,
Block block) {
{noformat}
The fix is trivial; delete the optional = 3. Also add a spec for instance_exec
somewhere (as a rubyspec and as a test in JRuby since we don't run 1.8.7 specs
yet), and add an error to the invocation handle generator to disallow both
optional and rest in an annotation *OR* fix it to just treat it as rest.
