How to change logging level?

[dcronkite]

How can I alter the logging level when running Metamaplite? I'd like to set it to at least WARN in order to reduce the amount of console output when running the application, but I can't seem to change the defaults.

I tried (on 3.6.2rc8):

• Running metamaplite.bat but changing 'debug' to 'warn' in config/log4j2.xml
• Specifying the changed log4j2.xml file with both the parameters log4j.configurationFile and metamaplite.log4jconfig in metamaplite.bat
• Passing in the --log4jconfig option to point to config/log4j2.xml (this results in an error: Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 at gov.nih.nlm.nls.ner.MetaMapLite.main(MetaMapLite.java:1323)).
