Description

additionalJvmArgs is assumed to be non-null when fork=true, but that is not the case when running on a non-modular JDK and not specifying explicitly a non-empty value for additionalJvmArgs in the configuration XML.

In the case were requiresModules=true a null value is changed to an empty string, but if requiresModules is false the null value remains.

        if (fork) {
            String[] split = additionalJvmArgs.split("\\s+");

Caused by: java.lang.NullPointerException
at org.apache.cxf.maven_plugin.Java2WSMojo.initArgs (Java2WSMojo.java:296)

Work-around is to specify a non-empty value for <additionalJvmArgs> , e.g. <additionalJvmArgs>-Dworkaroundnpe</additionalJvmArgs>
