[jboss-jira] [JBoss JIRA] (JASSIST-150) Performance problem with loading classes under certain circumstances

Performance problem with loading classes under certain circumstances -------------------------------------------------------------------- Key: JASSIST-150 URL: https://issues.jboss.org/browse/JASSIST-150 Project: Javassist Issue Type: Enhancement Affects Versions: 3.15.0-GA Reporter: Bruce Garner Assignee: Shigeru Chiba Attachments: Jassist150.java, Javassist150src.zip There is a performance problem in the class loading in javassist. Under certain circumastance the parse of the code will mean that javassist will attempt to load classes starting at the base of the package, and get failures for the package base until it finds the class. There is no caching of this failure so each attempt to load the class searches the entire classpath and fails. Unfortunately the code in PowerMock exercises this bug, and in large systems with may items on the classpath, large numbers of classes and large classes the process can be slow.
