Plugin does not log debug messages

Hi everyone
I developed plugin and it perfectly log debug events on remote server. Then I setuped Jira software local and plugin doesn’t log debug events anymore on local computer and it write only:

[DEBUG]: BeforeInstantiation [bean=class.name, type=class.name]
[DEBUG]: AfterInitialisation [bean=class.name, type=class.name]
Logging level is Debug.

log4j.properties:
log4j.appender.testplugin=com.atlassian.jira.logging.JiraHomeAppender
log4j.appender.testplugin.File=testplugin.log
log4j.appender.testplugin.MaxFileSize=20480KB
log4j.appender.testplugin.layout=org.apache.log4j.PatternLayout
log4j.appender.testplugin.layout.ConversionPattern=%d{dd-MM-yyyy HH:mm:ss.SSS} [%4p]: %m%n

log4j.logger.com.testplugin = DEBUG, console, testplugin
log4j.additivity.com.testplugin= false

Can you help me?
JIRA’s version 7.1.2 (server)

How do you start the local JIRA? Are you sure it consumes your log4j.properties? Does it create any log files at all in JIRA home?
