ArrayIndexOutOfBoundsException in JavadocUtil.getIncludedFiles

When executing javadoc:jar with <excludePackageNames>*</excludePackageNames> (or other values) we get :

java.lang.ArrayIndexOutOfBoundsException: 0
at org.apache.maven.plugin.javadoc.JavadocUtil.getIncludedFiles(JavadocUtil.java:369)

This is probably related to this code :

String[] excludeName = excludePackages[k].split( "[*]" );
...
if ( excludeName.length > 1 )
{
...
}
else
{
if ( fileList[j].startsWith( sourceDirectory.toString() + File.separatorChar + excludeName[0] ) )
...

If the split() function returns an empty array (excludeName), we reach the "else" branch but "excludeName[0]" will throw java.lang.ArrayIndexOutOfBoundsException: 0
