The error occurs when following code is executed:
{code}URL fileUrl = ClassLoaderUtil.getResource(fileName, clazz);
if ((checkFile && fileManager.fileNeedsReloading(fileUrl.toString())) ||
!validatorFileCache.containsKey(fileName)) {{code}
with fileName = Object-validation.xml
this file doesn't exists, so getResource returns null.
