[opencms-dev] Issue with OpenCms 10.5.3

[Daniel Seidel]

Hi Nivedita,

Java 17 is not supported for OpenCms 10.5.3, even Java 11 support start 
only at OpenCms 11 (see release notes 
https://www.opencms.org/en/article/OpenCms-11-available/). Official 
support for Java 17 and 21 is added with OpenCms 17 
(https://www.opencms.org/en/article/OpenCms-17-release-notes/) This 
might cause your issues.

Best, Daniel.
