OpenPojo Java 9 Compatibility Workaround

I am working on updating applications at work to Java 9. I have been using OpenPojo for years to test all my POJOs in one go. However, I found that the tests started throwing the exception:

java.lang.NoClassDefFoundError: Could not initialize class com.openpojo.reflection.java.packageloader.Package

I traced through the OpenPojo code and found that it was hard coded to read the Java class path from the old "sun.boot.class.path" system property. This property has been completely removed from Java 9, in favor of "java.class.path," which has been available since at least Java 7. (See https://docs.oracle.com/javase/8/docs/technotes/tools/windows/findingclasses.html)

I submitted my findings in an issue for the developers consideration: https://github.com/oshoukry/openpojo/issues/108

In the meantime, I developed the following workaround that can be inserted into a current POJO test class, and will allow the code to function the same way in Java 9.
