It makes sense to add it so that the test is skipped if there's not
enough of memory.
However, I think the actual requirement is >= 2G as it needs 1G for Java
heap and it needs native memory for images and for other purposes.
The test exhausts the available native memory to make malloc fail. The
amount of used memory reaches close to 2G before it fails.

Please review the fix for jdk11:
When the JVM is run with limited amount of memory, initCubemap
function called from BufImg_SetupICM can return NULL. It can lead to
a crash. It usually happens when native memory is exhausted and
malloc fails. In this state, JVM itself is not stable.
Adding NULL-check can prevent the crash in this particular place.
However, if the app continues, since native memory is exhausted and
malloc fails, JVM can still crash in another place.
Thank you in advance.
