Example 6 with EUnexpected

use of com.accenture.trac.common.exception.EUnexpected in project tracdap by finos.

the class StartupSequence method initLogging.

/**
 * Initialize the logging framework.
 *
 * <p>Logging can be configured by setting the property logging.url in the config
 * section of the root configuration, to point to the location of a logging config file.
 * TRAC uses Log4j2 as a backend for slf4j, so the logging config file must be a valid
 * log4j2 config file. If no logging config is provided, messages will be logged
 * to stdout.</p>
 *
 * <p>This method should be called immediately after calling initConfigPlugins(),
 * since it uses the config loading mechanism which relies on those plugins being
 * available.</p>
 *
 * @throws EStartup There was an error processing the logging config
