Description

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.getDefaultFi
lterWrappers(DefaultMavenFileFilter.java:217)
        at org.apache.maven.shared.filtering.DefaultMavenFileFilter.copyFile(Def
aultMavenFileFilter.java:76)

This happens when the following situation occurs:

// request.getFileFilters()  is null
buildFilters.removeAll( request.getFileFilters() );

Root cause: https://bugs.openjdk.java.net/browse/JDK-8015656
So let's do the null check in the maven-filtering codebase.
