[...]/ByteBufferKaitaiStream.java:87: error: unknown tag: implNote

Building the runtime using mvn package an JDK 8 fails for me because the non-standard Javadoc-tag @implNote is used. I get the following error:

Non-standard because of the following:

There are no plans to attempt to popularize these particular tags outside of use by JDK documentation.

There's a workaround for the javadoc-plugin for Maven which works if I adopt your pom.xml, but that has a drawback:

By default all new tags are added to the end of the generated doc, which puts them below, e.g., @param and @return. To change this, all tags have to be listed in the desired order, so you have to add the known tags to the list below the three above:[...]

So, how do you want to handle this, by removing the tag or adopting pom.xml? And if the latter, how? Add all "new" tags or only the used one, care about their order...?
