(11) RFR (S) JDK-8196601: IllegalAccessError: cannot access class jdk.jfr.internal.handlers.EventHandler

[Lois Foltan]

Please review this partial back out of a recent change that caused 
incorrect class accessibility checks to occur in the case of calls to 
java/lang/Class::getDeclaredFields as well as within JVM signature 
stream processing.  Testing exposed the issue where a call to 
getDeclaredFields resulted incorrectly in an IllegalAccessError.

Thanks,
