RHBA-2014:1804 - Bug Fix Advisory

Topic

Updated java-1.6.0-openjdk packages that fix one bug are now available for Red
Hat Enterprise Linux 6.

Description

The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment
and the OpenJDK 6 Java Software Development Kit.

This update fixes the following bug:

• Prior to this update, a race condition in some cases occurred between two

system calls used to access Java annotations: isAnnotationPresent() and
getAnnotation(). This caused the system to enter a deadlock. With this update,
Java annotation data and the reflection API data in the Java class object have
been moved into a wrapper class, and access to the data has been restricted to a
set of atomic operations. As a result, the race condition no longer occurs,
which in turn prevents the mentioned deadlock. In addition, the value type
applied when retrieving a static field on an OpenJDK 6 virtual machine has been
corrected. (BZ#1158799)

Users of java-1.6.0-openjdk are advised to upgrade to these updated packages,
which fix this bug. All running instances of OpenJDK Java must be restarted for
the update to take effect.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
