[jira] [Commented] (LOG4J2-379) Problem using log4j2 in Google App Engine

    [ https://issues.apache.org/jira/browse/LOG4J2-379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13756196#comment-13756196 ] 

Ralph Goers commented on LOG4J2-379:
------------------------------------

I believe I have a fix for this but I don't know how to test it. Can you provide a unit test? I checked in what I think is the fix in revision 1519489.

> This seems to be caused by the {{OnStartupTriggeringPolicy}} class initializing a static field with this code:
> {code}
> private static final long JVM_START_TIME = ManagementFactory.getRuntimeMXBean().getStartTime();
> {code}
> Is there a workaround for this?
