SoftReferences not cleaned up

[Nicolae Mihalache]

Hello,

I have problems understanding why the SoftReferences are not cleaned up.
This is my version of java:
java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

and I run it with the options -Xmx512m  -XX:SoftRefLRUPolicyMSPerMB=1

Still the number of SoftReferences keep increasing and I see that some of
them are 30+ hours old. I have a heap dump:
https://drive.google.com/open?id=0B8_hkIRtZSShNUtTZUx3UTFuMEk

I don't know how to debug further, any hint would be appreciated.

thanks,
nicolae
