Re: ClassNotFoundException at HostServicesDelegate

[Kevin Rushforth]

A workaround is:

   java -addmods javafx.deploy ....

We will need a fix that doesn't require this.

Hi Kevin,

I use JDK 9 EA b124 for Windows x64 from java.net <http://java.net>.

If you want to full stack trace, please download from here:

This exception does not occur on OracleJDK 8. So I guess this exception is from Java FX 9.

Thanks,

    Hi Yasumasa,

    I assume this is a download of the Oracle JDK from java.net
    <http://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?

        Hi all,

        When I ran HeapStats Analyzer [1] on JDK 9 EA b124, I
        encountered ClassNotFoundException as below:
        ------------
        java.lang.ClassNotFoundException:

                  :

        This message does not appear on JDK 8u92.
        I think this message is printed at [2].

        I think this exception message do not need to be printed.
        At least, it is debug level.

        Does someone work for it?
        If not so, I want to contribute patch.


        Thanks,

        Yasumasa
