Hi Aleksey, > http://cr.openjdk.java.net/~shade/8149835/webrev.jdk.01/
701 return (pkg != null ? pkg.getName().replace(".", "/") + "/" : "") + "Stubs$$StringConcat"; 702 } else { 703 return hostClass.getName().replace(".", "/") + "$$StringConcat”; Maybe you should use here the character based String#replace()-method as it is faster and does not produce as much garbage as the CharSequence based method does.
