Yes! this has helped me, I unregistered the Runtime bean and registered my proxy that filters clear text properties. Now if only I could find out find out what is invoking this with this very shallow stack trace (I guess from native): at java.lang.System.getProperties(System.java:628) at sun.misc.VMSupport.serializePropertiesToByteArray(VMSupport.java:75) but that's for another mailing list, here presented only as a curiosity (the first page of VisualVM is using this instead of Runtime JMX bean to access system properties) thank you :) zoran -- Zoran Regvart
