Using command line defined simple tag -tag 'apiNote:optcm:<em>API Note</em>'

If the tag uses {@inheritDoc} then the following exception is encountered.

The input command line was:

javadoc -verbose -d DocTest -tag 'apiNote:optcm:<em>API Note</em>' -tag 'implSpec:optcm:<em>Implementation Requirements</em>:' -tag 'implNote:optcm:<em>Implementation Note</em>:' -package DocTest.java

(DocTest.java is attached)
