--------------------------------------

Hello Rick,

Thank you for this report. What is your context name? In particular, does the context name contain special characters such as '<' or '>'  ?

> Hello Logback team,
> I encountered a unexpected behavior when trying to print out the log context name in the html output.
> I configured a FileAppender with the following layout:
> <layout class="ch.qos.logback.classic.html.HTMLLayout">
>                     <Pattern>%d{HH:mm:ss.SSS}%mdc{refId}%contextName%msg</Pattern>
> </layout>
> With this pattern, non of the log messages end up in the file. The output completely stops after the table header.
> If I remove "%contextName" from the pattern, I get my log messages written to the file as expected.
> Could you please have a look at this issue.
> Thank you in advance for your help.
> Kind regards,
> Rick
