Please review this fix for bug JDK-8177522 

The issue is windows only.

When two OnOutOfMemoryError options are passed to java, they are 
combined using '\n' as separator.

But when OnError parses the string, it only knows ';' as separator of 

On nix systems it works fine because the command with '\n' in it are 
passed to shell where it executed fine.

With this patch I'm making windows routine to behave similary to nix, 
passing command to cmd.exe for execution, I just have to replace all 
'\n' with '&'.

Such workaround is needed to not break compatibility with existing systems.

Testing: jprt, included testcase.
