Updated java-1.6.0-openjdk packages that fix two bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit.
- 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.
- 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.
In addition, this update adds the following
- 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.
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.
