RHBA-2012:0836 - Bug Fix Advisory

Topic

Updated java-1.6.0-openjdk packages that fix multiple bugs and add various
enhancements 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 Software Development Kit.

The java-1.6.0-openjdk packages have been upgraded to upstream version 1.11.1,
which provides a number of bug fixes and enhancements over the previous version.
(BZ#771971)

This update fixes the following bugs:

• Previously, after updating OpenJDK to

java-1.6.0-openjdk-1.6.0.0-1.40.1.9.10.el6_1, the Java Remote Object Registry
(rmiregistry) started only if run with the java.rmi.server.codebase argument,
otherwise the registry start failed. This update fixes the regression and the
registry can be started without the argument as expected. (BZ#751203)

• Channel binding for the Kerberos protocol was implemented incorrectly and

OpenJDK did not process Kerberos GSS (General Security Services) contexts which
did not have incoming channel binding. This resulted in interopability problems
with Internet Explorer on Windows Server 2008. With this update, OpenJDK handles
unset channel binding correctly and processes Kerberos GSS contexts as expected.
(BZ#767537)

• The SystemTap script translator (stap) run with jstack() systemtap support

could terminate with an error similar to the following:

ERROR: kernel read fault at 0x0000000000000018 (addr) near identifier
'@cast'
at /usr/share/systemtap/tapset/x86_64/jstack.stp:362:29

This update improves the jstack code including, for example, the constant
definition and error handling, and the stap script with jstack now works more
reliably. (BZ#804632)

• This update fixes multiple problems that occurred when using signed jar files.

(BZ#805936, BZ#807324)

In addition, this update adds the following enhancement:

• Support for huge pages was added. (BZ#751410)

All users of java-1.6.0-openjdk are advised to upgrade to these updated
packages, which fix these bugs and add these enhancements.
