Assignee: Claus Ibsen
> camel-xslt-saxon: doInit()/doStart() duplicate the parent lifecycle -
> stylesheet loaded and compiled twice on startup
> ---------------------------------------------------------------------------------------------------------------------
>
> Key: CAMEL-24109
> URL: https://issues.apache.org/jira/browse/CAMEL-24109
> Project: Camel
> Issue Type: Bug
> Components: camel-xslt
> Affects Versions: 4.21.0
> Reporter: Federico Mariani
> Assignee: Claus Ibsen
> Priority: Minor
> Labels: code-review
> Attachments: XsltSaxonDuplicateResourceLoadTest.java
>
>
> h3. Problem
> {{XsltSaxonEndpoint.doInit()}} calls {{super.doInit()}}, which already runs
> the complete parent sequence - {{setXslt(createXsltBuilder())}} (virtual
> dispatch, so it already creates the *Saxon* builder), {{loadResource(...)}}
> for classpath URIs, {{setProcessor(...)}} - and then repeats all three steps
> itself: a second builder is created (the first is discarded) and the
> stylesheet is resolved and compiled a second time.
> The same duplication exists in {{doStart()}} for non-classpath URIs: the
> parent {{doStart()}} dispatches to the overridden {{loadResource()}}, then
> {{XsltSaxonEndpoint.doStart()}} calls it again - an {{http:}} stylesheet is
> fetched and compiled *twice on every start*.
> Copy-paste remnant from the CAMEL-14176 module split. Wasteful (double
> compile, double remote fetch) and doubles any load-failure window.
> h3. Reproducer
> Attached {{XsltSaxonDuplicateResourceLoadTest.java}} - a counting
> {{URIResolver}} observes 2 top-level resolves of the stylesheet on endpoint
> startup where 1 is expected.
> h3. Fix direction
> Delete the duplicated bodies of {{XsltSaxonEndpoint.doInit()}}/{{doStart()}}
> (keep the {{super}} calls) - the parent lifecycle already does everything
> through the overridden virtual methods.
> ----
> _This issue was researched and filed by Claude Code on behalf of [~fmariani]
> (GitHub: Croway), as part of a code review of camel-xslt and
> camel-xslt-saxon. The attached JUnit reproducer fails deterministically on
> current main (4.22.0-SNAPSHOT); place it in
> {{components/camel-xslt-saxon/src/test/java/org/apache/camel/component/xslt/saxon/}}._
