Update: lost my patience. Installed another eclipse and it workimg now
Solution
It was a IDE issue, somehow it was picking Java17 even though after setting it to 15. Thank you all for your reply. It helped at least to know the root cause. I uninstalled the eclipse and re-installed a fresh one. It works now
