Description

Proposal from https://github.com/eclipse-jdt/eclipse.jdt.core/pull/2551

Raise a build path error with the same message as IProblem.JavaVersionNotSupported, so that users will find the blocking error on the project itself, not just on one random compilation unit.

Currently the first file we compile with not supported Java version is flagged with an error, not the project.

Contributor guide

Research direction
Examine the error reporting in org.eclipse.jdt.core that issues JavaVersionNotSupported and modify it to create a build path marker on the project instead of on a compilation unit. Look at the linked PR #2551 for guidance.
