blackberry-deploy and other tools cannot find java on Windows

How to reproduce:
1) Have a host-machine where you do not have any 'java' available on PATH env. var. i.e. when you open command-line and run 'java', it will print out: 'java command not found'
2) Start QtCreator, open Tools -> Options -> Devices -> Add... -> BlackBerry Device.
3) What the device auto-detection - it will quickly fail to detect any device - even through you have an API Level 10.2.0 or newer installer/registered.

This is becuase QtCreator runs:

PATH_TO_QNX_HOST/usr/bin/blackberry-deploy.bat -devices

but it does not set environment variables e.g. PATH properly and therefore blackberry-deploy.bat cannot run related 'java' program to run.

This is a critical issue and needs to be fixed as soon as possible.

Possible workaround:
Update all PATH_TO_QNX_HOST/usr/bin/*.bat files from:

@java ...

to:

@"FULL_PATH_TO_JAVA_HOME\bin\java" ...

e.g.:

@"C:\Program Files\Java\jre7\bin\java" ...
