> When using the launchpad plugin with java 8 I get an NPE with:
> Caused by: java.lang.NullPointerException
> 	at java.util.Objects.requireNonNull(Objects.java:203)
> 	at java.util.ArrayList.removeAll(ArrayList.java:674)
> 	at org.apache.maven.shared.filtering.DefaultMavenFileFilter.getDefaultFilterWrappers(DefaultMavenFileFilter.java:215)
> 	at org.apache.maven.shared.filtering.DefaultMavenFileFilter.copyFile(DefaultMavenFileFilter.java:75)
> 	at org.apache.sling.maven.projectsupport.AbstractUsingBundleListMojo.readSlingProperties(AbstractUsingBundleListMojo.java:411)
> 	at org.apache.sling.maven.projectsupport.AbstractUsingBundleListMojo.getSlingProperties(AbstractUsingBundleListMojo.java:460)
> It seems that while ArrayList#removeAll(null) does not throw with pre Java8 it now does
- the javadocs clearly state that a NPE is thrown, so we should adjust our code
