> Looking at ObjectName source code (e.g.
> http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/javax/management/ObjectName.java
> ) I can see that ":" is not a valid character, so my idea for solving this
> problem is to use:
> 1) URLEncode.encode() - seems to be more "proper" solution, but produces a
> bit unreadable metric scrope like: MBean
> org.apache.cassandra.metrics:type=Connection,scope=2001%3A4c27%3A10%3A167%3A0%3A1%3A2%3A5,name=CommandCompletedTasks
> 2) <String>.replaceAll() - we can simply replace ":" with "." which wouldn't
> give us valid IPv6 address, but will be much more readable.
> Second one seems to be a better choice for me, but I attach two patches.
