[jira] [Comment Edited] (LOG4J2-703) Android: Could not find class
'javax.naming.InitialContext', referenced from method
org.apache.logging.log4j.core.lookup.JndiLookup.lookup
[ https://issues.apache.org/jira/browse/LOG4J2-703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14057086#comment-14057086 ]

--------------------------------------------------------------
Committed revision 1609378.
The code now guards against this failure, logs a warning and continues on its merry way. You just will not be able to do JNDI lookups if JNDI is not there, like apparently, on Android.
Please test and close if it works for you.
