Thanks for the info.

>>From memory the problem is the inverting of the Priority and Level
classes. In 1.2, Priority extends Level while in 1.3 Level was to extend
Priority or somesuch. This works in a compatible manner for most
methods, but not the Logger.log(FQDN, level, msg, t) method - which JCL
uses. That's from memory many months old now, so may not be 100%

I discussed this issue with them last year and they were determined to
push on with their plan. They do have to get rid of the old stuff
eventually, but it's very interesting that they are now considering
holding off on that until a 2.0 release. I'll try to find time to talk
to them about that but I don't think it affects the proposed JCL 1.1
