Various javadoc HTML related errors/warnings in CI build

[srikanth-sankaran]

https://ci.eclipse.org/jdt/job/eclipse.jdt.core-Github/job/PR-3024/6/console has these diagnostics. These errors are perhaps not causing the build error but given that build failed it is not super illuminating or helpful to have the build log cluttered with such errors:

@jarthana - could these perhaps be related to the recent markdown changes ? Sorry if false blame. Thanks for taking a look.

[akurtakov]

Isn't this https://github.com/eclipse-jdt/eclipse.jdt.core/pull/3033 ?

[jarthana]

These errors are reported by Javadoc tool from the JDK and nothing to do with the compiler. We can simply fix the Javadoc in the source code and move on.

[jarthana]

Isn't this #3033 ?

OK, I see we already have a fix. Closing this one.
