Description Tomas Hoger 2019-07-16 10:13:11 UTC 
It was discovered that the AccessController class implementation in the Security component of OpenJDK failed, in certain cases, to consider the current context and correctly restrict privileges based on it.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

Public now via Oracle CPU July 2019:
