  JDK Internal API Usage Report for infinispan-6.0.2.Final-all

The OpenJDK Quality Outreach campaign has run a compatibility report to 
identify usage of JDK-internal APIs. Usage of these JDK-internal APIs 
could pose compatibility issues, as the Java team explained in 1996 
<http://www.oracle.com/technetwork/java/faq-sun-packages-142232.html>. 
We have created this report to help you identify which JDK-internal APIs 
your project uses, what to use instead, and where those changes should 
go. Making these changes will improve your compatibility, and in some 
cases give better performance.

Migrating away from the JDK-internal APIs now will give your team 
adequate time for testing before the release of JDK 9. If you are unable 
to migrate away from an internal API, please provide us with an 
explanation below to help us understand it better. As a reminder, 
supported APIs are determined by the OpenJDK's Java Community Process 
and not by Oracle.

This report was generated by jdeps 
<http://docs.oracle.com/javase/8/docs/technotes/tools/unix/jdeps.html> 
through static analysis of artifacts: it does not identify any usage of 
those APIs through reflection or dynamic bytecode. You may also run 
jdeps on your own 
<https://wiki.openjdk.java.net/display/JDK8/Java+Dependency+Analysis+Tool> 
if you would prefer.

Summary of the analysis of the jar files within infinispan-6.0.2.Final-all:

  * Numer of jar files depending on JDK-internal APIs: 10
  * Internal APIs that have known replacements: 0
  * Internal APIs that have no supported replacements: 73

      Identify External Replacements

You should use a separate third-party library that performs this
