Eclipse and GraalVM: "The VM does not support the Graal API"

[Doug Simon]

As of http://hg.openjdk.java.net/graal/graal/rev/c9284d733aa1, all classes in graal.jar (and graal-truffle.jar) are now (by default) isolated from application classes. This is part of efforts to secure Graal.

To revert to the old behavior, specify -XX:-UseGraalClassLoader on the command.
