Description

Since 2.3.4 update, loading xworks validator with
ActionValidatorManager#getValidators(Class, null) cause
null pointer exception.

Here is the stack trace:

Caused by: java.lang.NullPointerException
	at com.opensymphony.xwork2.validator.DefaultActionValidatorManager.loadFile(DefaultActionValidatorManager.java:330)
	at com.opensymphony.xwork2.validator.DefaultActionValidatorManager.buildClassValidatorConfigs(DefaultActionValidatorManager.java:237)

	at com.opensymphony.xwork2.validator.DefaultActionValidatorManager.getValidators(DefaultActionValidatorManager.java:74)

The error occurs when following code is executed:

URL fileUrl = ClassLoaderUtil.getResource(fileName, clazz);
if ((checkFile && fileManager.fileNeedsReloading(fileUrl.toString())) || !validatorFileCache.containsKey(fileName)) {

with fileName = Object-validation.xml
this file doesn't exists, so getResource returns null.
