I found the solution which is the 1.6 jdk update has a problem with redrawing. This problem also happens with Coldfusion 9 installation file. In order to check your JDK has the right update, use this command below from your terminal:
/usr/libexec/java_home -v 1.6 -exec java -version
If you got M4508, the update has a problem. Download the correct update from the Apple site using this following link: http://support.apple.com/kb/DL1572
