This looks the same as that problem someone was having on the web forums
with the EntityCmp task - if a particular subtask hasn't been included in
the <ejbdoclet>, then when the DD template calls getXXXClassPattern() the
getSubTaskBy() call returns null and we get a NPE...
I guess the various getXXXClassPattern()s could be modified to check for
the null first (and use the default pattern if it is?). Alternatively,
maybe it could use static equivalents of getXXXClassPattern() which do
likewise (i.e. check if the subtask is in use, return the specified
pattern if so, return the default if not)?
