Will Glass-Husain resolved VELOCITY-374:

> VE throws NPE if not initialized

> Key: VELOCITY-374
> URL: http://issues.apache.org/jira/browse/VELOCITY-374
> Project: Velocity
> Type: Bug
> Components: Source
> Versions: 1.5
> Environment: Operating System: other
> Platform: Other
> Reporter: Will Glass-Husain
> Fix For: 1.5

> VelocityEngine throws a strange NPE if it's not initialized. It'd be better
> if it threw an Exception with a meaningful error message.
> From [EMAIL PROTECTED] <[EMAIL PROTECTED]>
> I had another problem that I think can help others in the future. In looking
> through the archives I noticed other people having the same null pointer
> exception I was having. I went through the code and noticed that if a person
> did not "init()" a velocity engine, the resourceManager never gets
> initialized. When they call the function below in RuntimeInstance.java, they
> get the null pointer exception.
> public Template getTemplate(String name, String encoding)
> throws ResourceNotFoundException, ParseErrorException, Exception
> {
> return (Template)
> resourceManager.getResource(name,
> ResourceManager.RESOURCE_TEMPLATE, encoding);
> }
> ERROR [http8080-Processor2] TemplateToStringManagerBD.getContentAsString() -
> VelocityEngine failed to merge the template.
> java.lang.NullPointerException
