-------------------------------------
Summary: Replace String.replaceAll with substring for better
throughput performance
Key: CXF-8537
URL: https://issues.apache.org/jira/browse/CXF-8537
Project: CXF
Issue Type: Improvement
Components: JAX-RS
Affects Versions: 3.3.10
Environment: This would affect all platforms.
Reporter: Joshua Dettinger
Fix For: 3.4.4
Sometime in the JAX-RS 3.3.x branch, the method
org.apache.cxf.jaxrs.utils.JAXRSUtils.combineUriTemplates was introduced. This
method calls a costly String.replaceAll in order to remove a '/' character at
the end of a uri. This method can perform up to 2% better in throughput
scenarios by changing:
return parent.replaceAll("/$", "") + child;
to
return parent.substring(0, parent.length() - 1) + child;
