[jira] Created: (JCR-2896) WebdavResponseImpl should cache
TransformerFactory
WebdavResponseImpl should cache TransformerFactory
--------------------------------------------------
Key: JCR-2896
URL: https://issues.apache.org/jira/browse/JCR-2896
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-webdav
Affects Versions: 2.2.2
Reporter: Stepan Koltsov
JackrabbitResponeImpl.sendXmlResponse creates an instance of TransformerFactory on each invocation. We see, that this TransformerFactory initialization consumes significant amount of time, because of complex logic inside:

TransformerFactory can be cached in static field:
private static final TransofmerFactory transformerFactory = TransformerFactory.newInstance().
