> Project: Jackrabbit Content Repository
> Issue Type: Improvement
> Components: jackrabbit-jcr-commons, jackrabbit-jcr2spi
> Reporter: Lars Grefer
> Assignee: Julian Reschke
> Priority: Major
> Labels: candidate_jcr_2_12, performance
> Fix For: 2.14.9, 2.20.1, 2.22, 2.21.1, 2.18.6, 2.16.7

> While profiling our application, I noticed that {{org.apache.jackrabbit.commons.xml.ParsingContentHandler#parse}} creates a new {{SAXParserFactory}} instance on every invocation.
> This is quite expensive because {{SAXParserFactory.newInstance()}} internally scans the whole classpath for {{META-INF/services/}} declarations.
> I therefore propose this patch: https://github.com/apache/jackrabbit/pull/90
