JDK 21 resolution not working?

[guw]

Can someone help me understand the following output from Tycho?

Most likely your target platform is on older version . Make sure it has smth like https://github.com/eclipse-m2e/m2e-core/blob/1154ef779cd8027729cbc5540c58ed40c6335d70/target-platform/target-platform.target#L4
