> Benchmarking shows that the java.util.UUID.fromString() method is 10 times slower than
the previous version we used from jackrabbit-jcr-commons. This method is quite heavily used
in the query section or more generally whenever a NodeId is created from a String.
> I'd like to introduce the custom String UUID parsing code again that we had in the jackrabbit-jcr-commons
UUID class and use it in the NodeId(String) constructor.
> WDYT?
