Description
FULL PRODUCT VERSION :
A DESCRIPTION OF THE PROBLEM :
Nashorn version: hg tip 18edd7a1b166
The implementation for case-insensitive regular expressions does not comply to [ES5.1 - 15.10.2.8 Canonicalize]. This applies to both implementations, java.util.regex and Joni.
I've noticed this while working on integrating Joni for my project. You should be able to port the necessary changes from here [1]:
- UCS2Encoding.java contains the relevant changes for runtime.regexp.joni.EncodingHelper
- RegExpParser.java#L1256-L1412 contains the relevant changes for the java.util.regex based implementation
