ClassNotFoundException at HostServicesDelegate

[Kevin Rushforth]

Hi Yasumasa,

I assume this is a download of the Oracle JDK from java.net? We haven't 
seen any problems like this, so it might be a problem with HeapStats 
analyzer. The class in question is a closed-source class that lives in 
the javafx.deploy module. What exactly are you running?
