jdk/javadoc/tool/removeOldDoclet/RemoveOldDoclet.java tries to use OldDoclet.jasm which has reference to removed API com.sun.javadoc.

Fix for JDK-8219575(jdk/javadoc/tool/removeOldDoclet/RemoveOldDoclet test fails in mach5), tries to solve the testcase failure with handling of NoClassDefFoundError

This issue is created to remove the reference to the old API in the testcase and also the corresponding handling of the NoClassDefFoundError in jdk/javadoc/internal/tool/Start.java
