Test vmTestbase/gc/memory/Nio/Nio.java
fails if unable to allocate all direct memory.

It assumes all direct memory is available which might be not correct.

This test is very sensitive to changes in the implementation. I suspect the issue at the time was the console I/O support that is no longer used. The test is passing now so I will close this issue.

I checked that loom allocate small amount of native memory by default (3 direct buffers). It cause test failure.
