Ambiguous method warnings in core_ext/object.rb in 9k #2104
Description
When I run jruby-head I get these warnings (I get it whenever a JRuby process starts up when I run tests with rspec and when I run bundle):
file:/Users/theo/.rvm/rubies/jruby-head/lib/jruby.jar!/jruby/java/core_ext/object.rb:27 warning: ambiguous Java methods found, using isJavaIdentifierStart(int)
file:/Users/theo/.rvm/rubies/jruby-head/lib/jruby.jar!/jruby/java/core_ext/object.rb:28 warning: ambiguous Java methods found, using isJavaIdentifierPart(int)
Looks like it's this method:
