This issue is reported by Marketing Wen.Huang@Sun.com for one PHP community guy, who wanted
to try out NB for PHP but NB kept crashing on start. 

Customer machine configuration:
OS X 10.5.5; 64 bit Core 2 Duo (intel); javac 1.5.0_16

Wen can reproduce the issue on his Mac notebook too (both full version of NB 6.5 RC2 and
NB 6.5 RC2 PHP), but with a different version of jdk:
OS X 10.5.5; 64 bit Core 2 Duo (intel); javac 1.6.0_07

Wen's steps:
------------
if I am pointing to Java 1.6 (java -version : "1.6.0_07"), the IDE will not run.

switching to Java 1.5 (java -version :"1.5.0_16") It works fine.  Also, I tried specifying the
JDK home in the netbeans.conf file (changing it to 1.5 or 1.6 does not seem to affect start up
at all).

So it looks like:
- either I have a corrupt version of 1.6 installed, or there is something broken with NB on 
Mac on Java1.6

To reproduce:
check java -version (see if it's 1.6.0_07)  (this is the latest Java update for Mac)
install NetBeans 6.5rc2
start IDE 
IDE will not run
