Problem defining method with default param in first position.  Seems OK for 
1.9.  See below:

C:\>jruby --1.9 -S jirb
irb(main):001:0> def qtest(a="foo",b);puts "hello";end;qtest(1,2)
hello
=> nil
irb(main):002:0> exit

C:\>jruby -S jirb
irb(main):001:0> def qtest(a="foo",b);puts "hello";end;qtest(1,2)
SyntaxError: (irb):1: syntax error, unexpected tRPAREN

def qtest(a="foo",b);puts "hello";end;qtest(1,2)
                   ^
        from (irb):1
irb(main):002:0> def qtest(a,b);puts "hello";end;qtest(1,2)
hello
=> nil
irb(main):003:0> def qtest(a,b="bar");puts "hello";end;qtest(1,2)
hello
=> nil
irb(main):004:0> def qtest(a="foo",b="bar");puts "hello";end;qtest(1,2)
hello
=> nil
irb(main):005:0> def qtest(a="foo",b);puts "hello";end;qtest(1,2)
SyntaxError: (irb):5: syntax error, unexpected tRPAREN

def qtest(a="foo",b);puts "hello";end;qtest(1,2)
                   ^
        from (irb):5
