Bug description:
  tested on armel oneiric using testcase:
  /usr/lib/jvm/java-7-openjdk-armel/bin/java -jamvm -verbose:jni -version

  output:
  xranby@ac100-oneiric:~$ /usr/lib/jvm/java-7-openjdk-armel/bin/java -jamvm -verbose:jni -version
  [Failed to open library /usr/lib/jvm/java-7-openjdk-armel/jre/lib/arm/libjava.so: libjvm.so: cannot open shared object file: No such file or directory]
  Error initialising natives: couldn't open libjava.so: use -verbose:jni for more information
  Error initialising VM (initialiseNatives)
  Error: Could not create the Java Virtual Machine.
  Error: A fatal exception has occurred. Program will exit.

  workaround:
  cd /usr/lib/jvm/java-7-openjdk-armel/jre/lib/arm/
  sudo ln -s jamvm/libjvm.so .

  expected output:
