When I run any surefire test (with reuseForks=false) that uses java.sql classes on jdk-9 it fails with:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test (default-test) on project maven-surefire-plugin-example: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test failed: java.lang.NoClassDefFoundError: java/sql/SQLException: java.sql.SQLException -> [Help 1]

If I run it with reuseForks=true it works fine.

Has anyone seen this error yet?

I thought I would check with this list before submitting a request to the surefire team. A trivial reproducer is attached.
