Since Hudson 1.349, console notes can be embedded into the console output file. These notes are stored in an encoded format and are intended to be stripped out before the console is displayed.

The Log Parser Plugin, since it reads from the console output file directly, puts these encoded notes into the Parsed Console Output page. Here is an example:

The attached patch JENKINS-7263.patch strips out these console notes.
