+/**
+ * What the test does.
+ * Preparation stage:
+ * Fill out ~90% of the heap with objects, each object is an object array.
+ * If we want to allocate K objects per region, we calculate N to meet:
+ * sizeOf(Object[N]) ~= regionSize / K
+ * Stress stage:
+ * No more allocation, so no more GC.
+ * We will perform a number of iterations. On each iteration i,
+ * for each pair of regions Rx and Ry we will set c[i] references
+ * from Rx to Ry. If c[i] less than c[i-1] at the end of iteration
+ * concurrent mark cycle will be initiated (to recalculate remembered sets).
+ * As the result RSet will be growing up and down, up and down many times.
+ *
+ * The test expects: no crash and no timeouts.
+ *
+ * Test Parameters:
+ * args[0] - number of objects per Heap Region (1 - means humongous)
+ * args[1] - number of regions to refresh to provoke GC at the end of cycle.
+ * (0 - means no GC, i.e. no reading from RSet)

-/**
- * What the test does.
- * Preparation stage:
- * Fill out ~90% of the heap with objects, each object is an object array.
- * If we want to allocate K objects per region, we calculate N to meet:
- * sizeOf(Object[N]) ~= regionSize / K
- * Stress stage:
- * No more allocation, so no more GC.
- * We will perform a number of iterations. On each iteration i,
- * for each pair of regions Rx and Ry we will set c[i] references
- * from Rx to Ry. If c[i] less than c[i-1] at the end of iteration
- * concurrent mark cycle will be initiated (to recalculate remembered sets).
- * As the result RSet will be growing up and down, up and down many times.
- *
- * The test expects: no crash and no timeouts.
- *
- * Test Parameters:
- * args[0] - number of objects per Heap Region (1 - means humongous)
- * args[1] - number of regions to refresh to provoke GC at the end of cycle.
- * (0 - means no GC, i.e. no reading from RSet)
- * args[2] - timeout in seconds (to stop execution to avoid jtreg timeout)
