JDK 9 RFR of JDK-8172475: Remove <tt></tt> usage from Class and ClassLoader

[joe darcy]

Hello,

The javadoc for java.lang.Class and java.lang.ClassLoader has some 
usages of the <tt></tt> HTML tag. This tag is not part of HTML 5 and has 
been replaced with <code></code>. In javadoc, direct use of <tt></tt> or 
<code></code> is rarely necessary since the {@code } tag can be used 
instead. In addition, ClassLoader has multiple extraneous usage of 
<tt></tt> inside the target of a {@link} tag; these usages should be 
removed.

Please review this webrev which addresses those issues:

Thanks,
