VisualVM on ubuntu(lucid) failed to initialize the Profiler engine

I installed VisualVM on my lucid(amd64), luanch it and it shows an error.
Failed to initialize the Profiler engine: Problem with a required JFluid installation directory or file /usr/lib/jvm/java-6-openjdk/lib/visualvm/profiler3/lib/deployed/jdk16/linux-amd64/ Original message: File does not exist.
In sprite of this error, the visualvm still can run but profiler/sampler doesn't show up.
Someone have filed this bug here. To fix this problem, recompile the missing lib manually and move to the right place.
Here are the steps
  1. Download visualvm source here (visualvm_1.2.2.orig.tar.gz at the right pane)
  2. Extract it and cd to the build directory
    tar -xzvf visualvm_1.2.2.orig.tar.gz
    tar -xzvf netbeans-profiler-visualvm_release68.tar.gz
    cd lib.profiler/native/build
  3. You will see build script ( ) then edit it. 
    1. Replace gcc32 with gcc
    2. Change 2 BuildJDK lines to below. /usr/bin/jvm/default-java/ is my jdk path; yours may differ.
      BuildForJDK "/usr/lib/jvm/default-java" "jdk16"
  4. Make directory for release
    mkdir -p ../../release/lib/deployed/jdk16/linux-amd64/
  5. Run this build script. It will compile the source against jni headers in our jdk and output as
  6. Move to the right place in your jdk path
    sudo cp ../../release/lib/deployed/jdk16/linux-amd64/ /usr/lib/jvm/default-java/lib/visualvm/profiler3/lib/deployed/jdk16/linux-amd64/
  7. Launch VisualVM again.
