      Known good settings of SoftRefLRUPolicyMSPerMB on internal applications and further testing by [~huntch] on some benchmarks showed that the default value of SoftRefLRUPolicyMSPerMB of 1000 is suboptimal.

      A value of 500 seems to be much better, reducing soft reference processing (and pause times) significantly, particularly in conjunction with JDK-8215232.
