[logback-user] creating an OutputstreamAppender

[Michael Guymon]

Hello Logbackers,

I am trying to manually create an OutputstreamAppender that writes to a 
ByteArrayOutputStream. I am stumped by a NPE at 
LayoutWrappingEncoder.doEncode(LayoutWrappingEncoder). Here is a gist 
what I have so far[1]. From all the examples I found on the web, it 
appears correct. Sadly, it does not work.

What I find odd is that I am passing in a PatternEncoder, so how is the 
LayoutWrappingEncoder being called?  My understanding was 
LayoutWrappingEncoder was for deprecated Layouts.

Any help would be greatly appreciated.
