* We have a tricky class loading issue to solve. GlassFishRuntime looks for an implementation of RuntimeBuilder.
* In case of OSGi, the implementation class is OSGiGlassFishRuntimeBuilder. OSGiGlassFishRuntimeBuilder has
* compile time dependency on OSGi APIs, which are unavoidable. More over, OSGiGlassFishRuntimeBuilder also
* needs to locate OSGi framework factory using some class loader and that class loader must share same OSGi APIs
* with the class loader of OSGiGlassFishRuntimeBuilder. Since we don't have the classpath for OSGi framework
* until main method is called (note, we allow user to select what OSGi framework to use at runtime without
* requiring them to add any extra jar in system classpath), we can't assume that everything is correctly set up
* in system classpath. So, we create a class loader which can load GlassFishRuntime, OSGiGlassFishRuntimebuilder
* and OSGi framework classes.
