adevroy commented on MNG-3728:
------------------------------

 1.) JAVA_HOME = C:\Program Files\Java\jdk1.6.0_03;C:\jai-1_1_2

The JAVA_HOME variable is expected to point to a single directory only, it is 
not meant to be a list of multiple paths. Out of curiosity, could you point us 
to the documentation that suggested to set JAVA_HOME that way.

I didn't do it my self when i installed JAI it added the path automatically .. 
i didn't even knew that it was there till the time maven started showing 
problem ( i didn't knew it was illegal :) )

    2.) JAVA_HOME = C:\Program Files\Java\jdk1.6.0_03;

Again, a single directory spec shouldn't end with a separator like ";"

i remove it and maven worked !!

3.) JAVA_HOME = C:\Program Files\Java\jdk1.6.0_03\

Although the trailing back slash is not necessary, this should work. I just 
tried

Yes it works i retried it ... i guess i had tried with the earlier version of 
maven this format ... must have failed cos of that !!

and thanks a lot  ...first for again getting me started and second telling me 
JAVA_HOME can't have multiple paths
