-------------------------------------

             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;
