On Java 9+ the bundle class loader should call ClassLoader.getDefinedPackage

[tjwatson]

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=490735#c9

On Java 9+ the classloader should call ClassLoader.getDefinedPackage instead of ClassLoader.getPackage to avoid delegation to the parent class loader.

@tjwatson I removed the stale flag as I think its still an issue, do you think you can address this probably for the current release?

I can try to take a look, but for such an old issue nobody has noticed it is not the highest priority.

Removing stale tag again. I will say I have little interest in fixing this until the framework can move up Java levels.

1. Nobody but me has observed there is any issue here
2. I worry about adding optional reflection for performance reasons to allow the framework to still use Java 8.

I don't know how isolated the change would be, but Tycho already supports building Multirelease-Jars if that's an option for you? so if this can be e.g. an abstract base class that has one java 8 variant and one java 9 it could work quite seamlessly.

I don't think the problem is important enough to add any level of complication.
