JDK 10 jlink outputs "Error reading module: jdk11/jmods/java.security.sasl.jmod" when linking JDK 11 modules which has a newer class file format version. The error message should be improved for example to output the cause of the exception.

$ jdk10/bin/jlink --verbose --module-path jdk11/jmods/ --output test-image --add-modules java.base -J-Djlink.debug=true
