On the main branch, not all parameters JavaDoc is rendered correctly in the documentation. An example is https://docs.wildfly.org/wildfly-maven-plugin/releases/5.0/dev-mojo.html#env. The code example seems to stop the documentation from rendering. When generating the documentation, there are some errors printed like:

line 1 column 81 - Error: <env> is not recognized!
line 1 column 87 - Error: <home> is not recognized!
line 1 column 51 - Error: <https:> is not recognized!
line 1 column 310 - Error: <galleon-options> is not recognized!
line 1 column 328 - Error: <jboss-fork-embedded> is not recognized!

It's not quite clear where these are coming from, but it appears to break rendering. This does not seem to happen in the 4.2 branch.
