-Xsoftrefthreshold

Sets the value used by the garbage collector to determine the number of garbage collections after which a soft reference is cleared if its referent has not been marked.

-Xsoftrefthreshold<number>

The default is 32, meaning that the soft reference is cleared after 32 * (percentage of free heap space) garbage collection cycles where its referent was not marked. For example, if -Xsoftrefthreshold is set to 32, and the heap is 50% free, soft references are cleared after 16 garbage collection cycles.
