KNOWN PROBLEMS

The following are known problems on the non-supported platforms.

• Behavior in conformance with the API specification is not guaranteed while running

as superuser on any version of Linux whose kernel was compiled with the

CONFIG_IP_TRANSPARENT_PROXY option. The default kernel shipped with the

Red Hat 6.2 distribution is compiled with this option. To avoid incompatibilities

associated with this problem, either do not use the Java platform while superuser or

else upgrade to a Linux operating system whose kernel was not compiled with the

CONFIG_IP_TRANSPARENT_PROXY option. Red Hat 7.1 and later versions ship

with the version 2.4 kernel which does not have this problem.

•When System.exit(int) is invoked on Red Hat 7.0, the program never exits

with a non-zero value. This problem is apparently due to a bug in the exit function in

libc.so library. To avoid this problem, use Red Hat 6.2 or Red Hat 7.1 rather than

7.0.

• If you use Red Hat Linux 7 Server, you must manually install compat-

libstdc++-6.21-2.9.0.0.i386.rpm to prevent "error while loading shared

libraries" when using the Java HotSpot VMs. This file is located in the /RedHat/

RPMS directory on the Red Hat Linux 7 CD-ROM. You may also obtain a copy of this

file from http://rpmfind.net. To install the file, use this command:

rpm --install compat-libstdc++-6.21-2.9.0.0.i386.rpm

It is not necessary to manually install compat-libstdc++-6.21-2.9.0.0.i386.rpm if you

are using Red Hat Linux 7 Workstation.

• Some early versions of Caldera OpenLinux use version 2.1.2-3 of glibc. Because that

version is not greater than or equal to 2.1.2-11, the Java 2 JRE's rpm installer fails

during its dependency check. We recommend that you obtain an updated version of the

glibc library available from Caldera at the following locations:

ftp.caldera.com:/pub/updates/eDesktop/2.4/current/RPMS

ftp.caldera.com:/pub/updates/eServer/2.3/current/RPMS

• An apparent bug in glibc 2.2-7 causes invalid hostnames of the form a.b.c.d.e to be

resolved as a valid address (a.b.c.d or a.b.c.e). This bug means that platforms that use

glibc 2.2-7 methods, such as java.net.InetAddresss.getByName(String

host), do not always throw an UnknownHostException, as they should, when

the hostname is invalid.
