Subject [jira] [Commented] (APLO-289) spaces in topic IDs get "\u0020" inserted before them
Date Fri, 25 Jan 2013 23:29:13 GMT


Christian Posta commented on APLO-289:

Looks like when we decode the destination, and create a new SimpleAddress, we encode the path
and that eventually calls DestinationAddress.escape(value)...

A simple test of:

    val s  = DestinationAddress.escape("this is a test")

will produce
this\u0020 is\u0020 a\u0020 test

This probably happens when we escape unicode characters...
Is space something we want to escape? Either way, if we escape it we can keep the original
space from being appended...

Hiram, am I on the right track? What's the anticipated behavior here?

the upgrade (there were definitely successful uses of topics with spaces in them before the
