Symptoms

Appian engines fail to reach RUNNING state, PRIMARY mode, and the following exception is printed in the service_manager.log file (located at <APPIAN_HOME>/logs):

java.lang.IllegalArgumentException: byte array given isn't the right length. Expected 256, was 257.

Cause

The alpha-numeric string in the Appian Engine Security Token, appian.sec (located at <APPIAN_HOME>/ear/suite.ear/conf), is being read as having 257 characters instead of 256 characters. This can happen when the appian.sec file is opened, even when the string contained in the file is not altered.
