Description

Hi,
the generated Help-Mojo Class contains malformed HTML which causes the generation of javadoc to fail under JDK 8. This is not reproducible with older Java versions (I suspect that oracle has deployed some more strict validation here).

error output is:

/fooBar/target/generated-sources/plugin/com/example/helpmojo/HelpMojo.java:311: error: malformed HTML

• @throws NegativeArraySizeException if <code>repeat < 0</code>
  ^
  /fooBar/target/generated-sources/plugin/com/example/helpmojo/HelpMojo.java:350: error: malformed HTML
• @throws NegativeArraySizeException if <code>indent < 0</code>
  ^

Command line was: /usr/lib/jvm/java-8-oracle/jre/../bin/javadoc @options @packages
[....]

using the following configuration:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-plugin-plugin</artifactId>
<version>3.4</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.plugin-tools</groupId>
