Updated java-1.7.0-openjdk packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Software Development Kit.
The java-1.7.0-openjdk package has been upgraded to upstream version 2.4.3, which provides a number of bug fixes and enhancements over the previous version.
- Attempting to compile a SystemTap script using the jstack tapset could have failed with an error similar to the following:error: the frame size of 272 bytes is larger than 256 bytesThis update corrects the jstack tapset and resolves this problem.
- Because of incorrect KDC list concatenation logic, the sun.security.krb5.Config.getKDCList method returned incorrect KDC lists when the dns_lookup_kdc property in the krb5.conf file was set to true. The concatenation logic has been fixed with this release and correct KDC lists are now returned.
- The java-1.7.0-openjdk RPM package contained incorrect specification of the libnss3 dependency and installed its x86_64 version on i686 systems. Because of the missing dependency, launching the java command with the -Dcom.sun.management.jmxremote parameter on 32bit JVMs terminated unexpectedly. The dependency specification has been corrected with this update. As a result, the correct version of the libnss3 package is installed and the java command no longer terminates when launched with the -Dcom.sun.management.jmxremote parameter.
- BZ#831734, BZ#905128
- The NSS security provider is now the default security provider in OpenJDK 7. This brings a significant performance improvement over the previous releases.
- The java-1.7.0-openjdk RPM package now provides the java dependency. As a result, it is no longer necessary to have the java-1.6.0-openjdk package installed alongside java-1.7.0-openjdk for the java dependency to be available.
Users of java-1.7.0-openjdk are advised to upgrade to these updated packages, which fix these bugs and add these enhancements. All running instances of OpenJDK Java must be restarted for the update to take effect.
