I was noticed that this is a stress test and should be properly marked
with "@key stress"
The test was also moved from test/gc/g1/ to tests/stress/gc.
New webrev: http://cr.openjdk.java.net/~dfazunen/8134963/webrev.02/
If you are interested in how an output from the test will look like:
----------System.out:(17/502)----------
%% Memory
%% used : 2M
%% available : 2045M
%% to allocate : 1840M
%% G1 Region Size: 1M
%% Objects:
%% Number of objects: 18400
%% objects in region: 10
%% N (array length) : 26210
%% Reference size : 4
%% Approximate size : 104840(102K)
%% Reference number : 1840
%% Execution:
%% Number of iterations: 15
%% Time spent: 10seconds
%% Free memory left: 195M
%% Test passed
Thanks,
Dima
----------System.err:(1/15)----------
