> 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
> Assignee: Freeman Yue Fang
> Priority: Minor
> Fix For: 3.5.0, 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;
