Robert Munteanu resolved SLING-13071.
-------------------------------------
Resolution: Fixed
> HTL use objects that adapt from the javax SlingHttpServletRequest cannot be instantiated in a Jakarta context
> --------------------------------------------------------------------------------------------------------------
>
> Key: SLING-13071
> URL: https://issues.apache.org/jira/browse/SLING-13071
> Project: Sling
> Issue Type: Bug
> Components: HTL
> Reporter: Robert Munteanu
> Assignee: Robert Munteanu
> Priority: Major
> Labels: sling-jakarta-servlet-javax-compat
> Fix For: Engine 3.0.2
>
>
> The following preconditions are sufficient to trigger the error:
> - app running in a Jakarta context ( e.g. Sling Starter 14-SNAPSHOT)
> - a HTL has a data-sly-use instruction for a Pojo without a default constructor
> - an AdapterFactory exists that adapts from SlingHttpServletRequest to the Pojo
> The {{JavaUseProvider}} will fail to adapt from the request and fall back to trying the default constructor, with an error such as
> {noformat}
> Caused by: java.lang.NoSuchMethodException: org.apache.sling.starter.testservices.exported.RequestHashCodePojo.<init>()
> at java.base/java.lang.Class.getConstructor0(Class.java:3187)
> at java.base/java.lang.Class.getDeclaredConstructor(Class.java:2491)
