RFR(XS): 8194232: Container memory not properly recognized.

[Doerr, Martin]

Hi Götz,

thanks for fixing it.

I wonder if 4 zeroes will be sufficient on all linux distros in the long run. Does anything speak against using e.g. 8 zeroes?

Best regards,
Martin

Hi 

Please review and sponsor this tiny fix. It needs to go to jdk10.
http://cr.openjdk.java.net/~goetz/wr17/8194232-ppcle_unlimited/webrev.01/

TestAggressiveHeap.java fails because the container recognition 
misinterprets the available memory size. On SLES 12.1 ppc64le, 
GET_CONTAINER_INFO() sets memlimit to 0x7FFFFFFFFFFF0000. This 
is compared to UNLIMITED_MEM == 0x7FFFFFFFFFFFF000, making 
the VM believe memory is _not_ unlimited.

Best regards,
  Goetz.
