[logback-dev] [JIRA] Commented: (LBCLASSIC-113) Nullpointer

[Ceki Gulcu (JIRA)]

Ceki Gulcu commented on LBCLASSIC-113:
--------------------------------------

Looking at the code it looks like the loggerContext field of the logger is null. This is impossible unless the said logger is a deserialized logger instance. Even in that case, the readResolve() method (n the Logger class line 824 ) should have returned a valid logger instance (one with a non-null loggerContext field). Is it possible that the logger instance was serialized with a custom  serialization?

Anyway, could you please provide more information so that I can reproduce this problem?
