Description Tomas Hoger 2020-04-12 16:07:12 UTC 
A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK.  The state machine of the regular expression Parser did not correctly handle empty string nodes in certain cases, which could cause an unexpected exception to be raised when processing a specially crafted regular expression.
