Mikhail Dobrinin updated LOG4J2-768:
------------------------------------
Description:
Creating a custom {{LogEventPatternConverter}} with mapping key {{T}} and
attempting to use it will *fail unpredictably* about 50% of the time on my
machine. At first it appeared to be a race condition, but after more inspection
the plugin names were the same. The plugin manager should probably throw some
kind of exception when it is registering a plugin whose name already is
registered. I am attaching a zip file which you can easily import as an Eclipse
project to reproduce.
*Succesful Output*:
