Robert Scholte closed MJAVADOC-517.
-----------------------------------
       Resolution: Fixed
    Fix Version/s: 3.0.1

Fixed in [c922342ed87805c236d68ccbf545efb17af0f965|https://gitbox.apache.org/repos/asf?p=maven-javadoc-plugin.git;a=commit;h=c922342ed87805c236d68ccbf545efb17af0f965]
I've replaced usage of SystemUtils from commons-lang3, so we should be good with every new version of Java.

> Under Java 10 RC, the plugin generates the following exception:
> {code:java}
> Caused by: java.lang.NullPointerException
>     at org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast (SystemUtils.java:1626)
>     at org.apache.maven.plugins.javadoc.AbstractJavadocMojo.getJavadocExecutable (AbstractJavadocMojo.java:3683)
>     at org.apache.maven.plugins.javadoc.AbstractJavadocMojo.executeReport (AbstractJavadocMojo.java:2001)
>     at org.apache.maven.plugins.javadoc.JavadocJar.doExecute (JavadocJar.java:190)
> {code}
> This seems to be down to the version string:
> {code:java}
> java version "10" 2018-03-20
> Java(TM) SE Runtime Environment 18.3 (build 10+43)
> Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+43, mixed mode)
> {code}
> {{commons-lang3}} version 3.5 can't deal with this, see https://issues.apache.org/jira/browse/LANG-1365 
> Inserting an explicit dependency on {{commons-lang3}} version 3.7 for the plugin works round the issue, and changing the dependency seems like the right fix for the next release of this plugin.
