Last updated on JULY 17, 2016

Applies to:

Java SE JDK and JRE - Version 8 and later
Information in this document applies to any platform.

Symptoms

Remote debugging sessions of a Java application sometimes appear to be hanging for 1-3 minutes on slow connections.  There are certain activities that trigger these pauses.  One of them is the first invocation of ClassLoaderReferenceImpl.visibleClasses() which loads a huge amount of information from the client JVM.
