Hi all,

could you please review the patch for TimSortStackSize2 test?

the test failed when externally passed (via -javaoption or -vmoption) -Xmx value is less than 770m or 385m, depending on UseCompressedOops. it happened because the test explicitly set Xms value, but didn't set Xmx.
now, the test sets Xmx as Xms times 2.

PS as it mostly affects hotspot testing, the patch will be pushed to jdk/hs.

testing: java/util/Arrays/TimSortStackSize2.java  w/ and w/o externally provided Xmx value
JBS: https://bugs.openjdk.java.net/browse/JDK-8190679
