Suppress startup error message if macro library not found
---------------------------------------------------------
Key: VELOCITY-720
URL: https://issues.apache.org/jira/browse/VELOCITY-720
Project: Velocity
Issue Type: Improvement
Components: Engine
Reporter: Will Glass-Husain
Priority: Minor
Ever since upgrading to Velocity 1.6.2 I get a stack trace when starting up due
to a missing macro library. The stack trace in particular makes for a very
noisy log. I suggest we do not print a stacktrace for a missing macro library
at startup.
Here's my settings
VelocityEngine ve = new VelocityEngine();
ve.setProperty("resource.loader", "class");
ve.setProperty("class.resource.loader.class",
"org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
ve.setProperty("class.resource.loader.cache", "false");
ve.setProperty("runtime.Log.invalid.references ", "false");
ve.setProperty("resource.manager.logwhenfound", "false");
ve.setProperty("runtime.log.logsystem.class",
"org.apache.velocity.runtime.log.SimpleLog4JLogSystem");
ve.setProperty("runtime.log.logsystem.log4j.category",
"com.forio.Velocity");
And here's the log report
2009-05-26 23:46:58 DEBUG Velocimacro : "velocimacro.library" is not set.
