Bug 518031 - Throw exception if unable to create a secured XML factory
Secured XML factory must be either successfully created or fail in an obvious way. Do not hide actual problem by catching an exception and let the caller to decide what to do with it. Change-Id: I8f3c6f29d2874dbb0f4952d1322150923582f642 Signed-off-by: Mykola Nikishov <mn@mn.com.ua>
