"Start Grails Console in Interactive Mode" fails

This report relates to IU-135-698; win8.1 all latest patches.

My Java SDK Home path set in the IntelliJ settings is:

R:\Program Files\Java\jdk1.6.0_45

If I press ^-Alt-G, then the "Start Grails Console in Interactive Mode", I get a cmd console containing:
```
ERROR: JAVA_HOME is set to an invalid directory: R:/Program Files/Java/jdk1.6.0_
45

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
```
Note the substitution of win-style '\' for *nix-style '/' path separators. I assume that this is the problem...

In the same window, I can do:
```
X:\DEVELOPMENT\IOS23\trunk>dir %JAVA_HOME%
Parameter format not correct - "Program".

X:\DEVELOPMENT\IOS23\trunk>dir "%JAVA_HOME%"
Volume in drive R is REST
Volume Serial Number is 5A9C-D6FE

Directory of R:\Program Files\Java\jdk1.6.0_45

A work-around MIGHT be to use R:\Progra~1\Java\jdk1.6.0_45, but the settings GUI will not allow one to specify this by hand.

For reference:
```

If I bring up a cmd window outside of IntelliJ, I can do:
```
Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.

C:\Users\>echo %JAVA_HOME%
%JAVA_HOME%

C:\Users\>
```
I always keep JAVA_HOME unset on my PC so that my path is uncluttered. I set is when needed, as needed.

Start by reproducing the Windows 8.1 failure through “Start Grails Console in Interactive Mode” using the ^-Alt-G shortcut and the configured Java SDK path. Trace how that entry point passes the IntelliJ Java SDK path to the command console; done means the console starts successfully with paths containing spaces and the existing SDK configuration.
