Thank you everyone for some good comments. I did not attach a formal
debugger, but I was able to brute force narrow down where the problem
is occurring: org.apache.juli.AsyncFileHandler. If I swap out
org.apache.juli.AsyncFileHandler with org.apache.juli.FileHandler then
the org.apache.juli.OneLineFormatter works just perfectly.
Here is the working configuration:
handlers = 1catalina.org.apache.juli.FileHandler,
2localhost.org.apache.juli.FileHandler,
3manager.org.apache.juli.FileHandler
.handlers = 1catalina.org.apache.juli.FileHandler
1catalina.org.apache.juli.FileHandler.level = ALL
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.
1catalina.org.apache.juli.FileHandler.formatter =
org.apache.juli.OneLineFormatter
2localhost.org.apache.juli.FileHandler.level = ALL
2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.
2localhost.org.apache.juli.FileHandler.formatter =
org.apache.juli.OneLineFormatter
3manager.org.apache.juli.FileHandler.level = ALL
3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
3manager.org.apache.juli.FileHandler.prefix = manager.
3manager.org.apache.juli.FileHandler.formatter =
org.apache.juli.OneLineFormatter
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = ALL
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers
= 2localhost.org.apache.juli.FileHandler
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level
= ALL
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers
= 3manager.org.apache.juli.FileHandler
A swap to AsyncFileHandler shows the problem. Most times I see
null.null for className and methodName, but sometimes the className is
filled in and the methodName is null. So, perhaps, under heavy load,
AsyncFileHandler doesn't behave predictably with respect to some
LogRecord fields.
