I have the same remark as Alan - I believe an `@deprecated ` text is needed in 
the API documentation of the public exported classes that are deprecated. At 
the minimum something like:

* @deprecated This class is deprecated for removal. There is no replacement. 


I also see that you have chosen to add `@SuppressWarnings` in tests. Not sure 
what the rules are for the serviceability area - but usually it's fine to keep 
the deprecation warning in tests (that is: suppressing deprecation warnings in 
tests is usually optional).

src/java.management/share/classes/javax/management/loading/MLetObjectInputStream.java
 line 43:

Shouldn't `MLetObjectInputStream` be deprecated for removal too? I mean - if 
MLet was removed - would we need to keep that class? If it were deprecated for 
removal too then I suspect that there would be no need to suppress the warning 
here (and below).

src/java.management/share/classes/javax/management/loading/MLetParser.java line 
156:

> 154:      * Scan an html file for {@literal <mlet>} tags.

> 156:     @SuppressWarnings("removal")

Same remark here. This class should probably be deprecated for removal too.
