java_send will not invoke a method taking a CharSequence #2881
Description
Consider the following in irb:
a = java.lang.StringBuilder.new
a.java_send :append, [java.lang.String], "I am Here\n"
puts a
yields I am Here as expected.
a.java_send :append, [java.lang.CharSequence], "I am not here!\n"
a.java_send :append, [java.lang.CharSequence], "I am not here!\n".to_java
both yield
TypeError: cannot convert instance of class org.jruby.RubyModule to class java.lang.Class

Lets get extreme and open Ruby's String as follows:
class String
include java.lang.CharSequence
def charAt(index)
self.to_java.charAt(index)
end
def length
self.to_java.length
end
def subSequence(start, endPoint)
self.to_java.subSequence(start, endPoint)
end
def toString
self.to_java.toString()
end
end
The code "SomeString".toString behaves as expected now, but:
a.java_send :append, [java.lang.CharSequence], "Some String"

Still fails :-(
