  [Issue]
- The fix of OpenJDK's bug 8158260 (http://icedtea.classpath.org/hg/release/icedtea7-forest-2.6/hotspot/rev/4f8cbd54a9c6) introduced 2 new native methods to the sun.misc.Unsafe class: isBigEndian0 and unalignedAccess0.

  This completely broke JamVM and as of now it is impossible to start a
  jamvm session.

  The simple fix is to add both methods to the natives.c file in the classlib/openjdk directory.
