Here's .bat script for unpacking "pack" files. Must be run in the root of unzipped JDK.

@echo off
echo **********************
echo unpack JDK pack-files
echo **********************
pause

set JAVA_HOME=c:\glassfish4\jdk7

setlocal enableextensions
for /r %%f in (*) do call :process %%f
endlocal
goto :eof

:process
if NOT "%~x1" == ".pack" goto :eof
set FOLDER=%~p1

set PWD=%CD%
pushd %FOLDER%
echo Unpacking %~nx1
%JAVA_HOME%\bin\unpack200.exe %~nx1 %~n1.jar
popd

goto :eof
