Public bug reported:

In both Ubuntu 11.04 and 11.10, the 64 bit version of openjdk-6-jdk
doesn't appear to have a copy of libjvm.so in:

/usr/lib/jvm/java-1.6.0-openjdk/jre/lib/amd64/client

C/C++ applications link against this file in order to use the Java
Native Interface (JNI). Without this library, JNI applications cannot
instantiate a Java virtual machine. Now there is of course the Cacao and
JamVM versions of libjvm.so in the amd64 folder, but this is not the
official JVM (to my understanding anyway and it doesn't work with my
app).

However, note that 32 bit version of the package indeed has libjvm.so at
the path:

/usr/lib/jvm/java-1.6.0-openjdk/jre/lib/i386/client

Is this a bug or is there just no 64 bit version of libjvm.so? I
searched the entire file system for an alternative and have Googled for
a while searching for the answer, but no success. I would appreciate any
help, the sooner the better.

Thanks!
