[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-3654) Reduce number of checks to see if Jbpm is installed in BusinessProcessContext

Reduce number of checks to see if Jbpm is installed in BusinessProcessContext ----------------------------------------------------------------------------- Key: JBSEAM-3654 URL: https://jira.jboss.org/jira/browse/JBSEAM-3654 Project: Seam Issue Type: Bug Components: Core Affects Versions: 2.1.0.GA Reporter: Michael Youngstrom Assignee: Michael Youngstrom Fix For: 2.0.3.CR2, 2.1.1.CR1 In my application profiling the SeamELResolver is an extremely hot spot. Although checking to see if jbpm is installed would appear a rather efficient process when done thousands of times a request it can become harmful. BusinessProcessContext.get is called every time an el expression is evaluated in a page. Here is a simple and I believe safe patch that will help make BusinessProcessContext more efficient. isJbpmInstalled() is only called once a request.
