Mark Struberg created XBEAN-274: ----------------------------------- Summary: Xbean finder is slow because of String.replaceFirst Key: XBEAN-274 URL: https://issues.apache.org/jira/browse/XBEAN-274 Project: XBean Issue Type: Bug Components: finder Affects Versions: 4.0 Reporter: Mark Struberg Assignee: Mark Struberg Fix For: 4.1
JarArchive uses entry.getName().replaceFirst(".class$", ""); This is effectively a replacement of the last ".class" in the entry name. This is pretty slow as replaceFirst internally creates a PatternMatcher. By replacing this line with an endsWith + substring I ended up with 20% performance boost. Overall in a real world application my OpenWebBeans boot time went down from 1020ms to 969ms. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
