OpenJDK disassembler plugin for HotSpot JVM (based on binutils)
Recent versions of HotSpot (including current builds of JDK7 and JDK6) can load a plug-in disassembler for diagnosing code quality.
This plugin comes from actual OpenJDK source repository (and is based on binutils tools for disassembler).
This is just a "repackaging" of original hsdis based on source code from http://hg.openjdk.java.net/jdk7u/jdk7u/hotspot/file/tip/src/share/tools/hsdis/
- Download this version of hsdis:
git clone git://github.com/drazzib/openjdk-hsdis.git
cd openjdk-hsdis
- Install build-dependencies
sudo apt-get install build-essential devscripts
sudo mk-build-deps -i -r

sudo debi --with-depends
sudo apt-get --purge remove openjdk-hsdis-build-deps
