JDK-6716785 - implicit null checks not triggering with CompressedOops
Description
JVM fails with the assertion 

  #  Internal Error (nmethod.cpp:1840), pid=7180, tid=1096018240
  # Error: guarantee(cont_offset != 0,"unhandled implicit exception in compiled code")

on linux-amd64 in -Xmixed mode with CompressedOops enabled.
Comments
EVALUATION This is also because of the implicit null checks failing because page below the Java Heap is accessible on linux.
