            Bug ID: 3467
           Summary: [systemtap] Hotspot object_alloc tapset uses
                    HeapWordSize incorrectly
           Product: IcedTea
           Version: unspecified
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: SystemTap
          Assignee: mark at klomp.org
          Reporter: sgehwolf at redhat.com

It multiplies the passed in argument ($arg4) by the HeapWordSize global. But
recent OpenJDK 8 passes in the correct value already. See:
http://hg.openjdk.java.net/jdk8u/jdk8u/hotspot/file/aa4ffb1f30c9/src/share/vm/runtime/sharedRuntime.cpp#l978

Besides, systemtap cannot read the HeapWordSize global reliably. See this
downstream bug for details:
