SoftReferences not cleaned up

[Nicolae Mihalache]

Here is a new output with PrintReferenceGC on:
https://drive.google.com/open?id=0B8_hkIRtZSShWTVpeVFONGlqVjQ

I see that each time when I run jmap -histo:live a few hundreds of them are
collected but still the number reported by jmap keeps increasing (5665 last
time it was run).
