In java.lang.management, the spec uses nested lists, lower-alpha ordered list, blockquote, and embedding a list in the @throws tag. JDK 6 javadoc was generated properly for these formatting but not in JDK 7 javadoc. A couple of examples:

http://download.oracle.com/javase/6/docs/api/java/lang/management/package-summary.html
http://download.java.net/jdk7/docs/api/java/lang/management/package-summary.html
   - the 2-level list formatting is lost

http://download.oracle.com/javase/6/docs/api/java/lang/management/ManagementFactory.html#newPlatformMXBeanProxy(javax.management.MBeanServerConnection,%20java.lang.String,%20java.lang.Class)

http://download.java.net/jdk7/docs/api/java/lang/management/ManagementFactory.html#newPlatformMXBeanProxy(javax.management.MBeanServerConnection,%20java.lang.String,%20java.lang.Class)
  - no bullet list in @throws specification.
