Description

When trying to run an specific webapp, which I unfortunately cannot provide, it fails with this NPE:

The affected line, https://github.com/apache/tomee/blob/master/maven/tomee-embedded-maven-plugin/src/main/java/org/apache/openejb/maven/plugins/TomEEEmbeddedMojo.java#L696, indicates we should drop or skip the properties with null values before adding containerProperties to properties.

 

Thanks in advance.
