RHBA-2014:1527 - Bug Fix Advisory

Topic

Updated java-1.6.0-openjdk packages that fix two bugs and add one enhancement
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 bugs:

• A bug previously caused the LineBreakMeasurer class to produce the

ArrayIndexOutOfBoundsException error when Java attempted to display certain
characters in certain fonts. This update fixes the bug and Java now displays the
affected characters correctly. (BZ#1112806)

• Prior to this update, an application accessing an unsynchronized HashMap could

potentially enter an infinite loop and consume an excessive amount of CPU
resources. As a consequence, the OpenJDK server became unresponsive. This update
prevents unsynchronized HashMap access from causing an infinite loop and as a
result, the OpenJDK server no longer hangs in the described scenario.
(BZ#1098399)

In addition, this update adds the following enhancement:

• Shared Java libraries have been modified to allow users to run Java with the

cap_net_bind_service, cap_net_admin, and cap_net_raw capabilities granted.
(BZ#1059925)

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

Solution
