---------------------------------------
Summary: NullPointerException with Java8 in AbstractUsingBundleList
Key: SLING-3142
URL: https://issues.apache.org/jira/browse/SLING-3142
Project: Sling
Issue Type: Bug
Components: Maven Plugins and Archetypes
Affects Versions: Maven Launchpad Plugin 2.2.0
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: Maven Launchpad Plugin 2.2.2
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.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
