Please review fix for: 7148499

[Kumar Srinivasan]

Hi,

Please review fix for launcher tests, the JVM requires a higher
stack size for 64bit systems, this fixes increases the stack size
and removes the test from the problem list.

fyi,
The stack size is specified here so that the launcher flag under
test,  parses and scales  these options for human readability.
