Huge memory usage by com.bea.common.security.utils.OrderedHashMap (Doc ID 1939905.1)

Last updated on NOVEMBER 05, 2016

Applies to:

Oracle WebLogic Server - Version 12.1.2.0.0 and later
Information in this document applies to any platform.

Symptoms

There are several JMS Queues on the server with jms service migration.

External applications, including standalone Java client and WebLogic Servers from other domain, will send and receive message to and from those JMS Queues.

The JMS Queues are enforced with security policy, such that, JMS Queue operations like "send", "receive" are only allowed by certain users.

There is a greater memory usage especially by a single instance of OrderedHashMap$Entry.
