    FULL PRODUCT VERSION : java version "1.8.0_72" Java(TM) SE Runtime Environment (build 1.8.0_72-b15) Java HotSpot(TM) 64-Bit Server VM (build 25.72-b15, mixed mode) Reproduced also with Java versions 1.7.0:60, 1.7.0_72, 1.7.0_80, 1.8.0_66, 1.8.0_71, 1.8.0_72. ADDITIONAL OS VERSION INFORMATION : Linux 3.13.0-67-generic #110-Ubuntu SMP Fri Oct 23 13:24:41 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Reproduced also on Windows 8 Pro [versione 6.2.9200] A DESCRIPTION OF THE PROBLEM : Loading a class within an application randomly throws a RuntimeException (or NullPointerException with Java7 versions). We can't reproduce the exception in our business application, but we provided a test application reproducing the same exceptions. The exception with Java 8: java.lang.RuntimeException: ERROR: Recovery got null entry at com.sun.deploy.cache.CacheEntry.recover(Unknown Source) at

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : The steps are: - cleaning up javaws cache - consuming heap memory causing OutOfMemoryError - loading a class contained in a signed jar of the application. Loading the class causes the exception. EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - Loading class successfully ACTUAL - It's impossible loading the required jar ERROR MESSAGES/STACK TRACES THAT OCCUR : Java Web Start 11.66.2.17 Uso della
