pvaccess and Java 9 Re: PVA Java status

["Kasemir, Kay" <kasemirk@ornl.gov>]

Hi:
Hi:

Kunal, for what it's worth, pva doesn't work with Java 9, because it's trying to use some corba(?!) classes.
For example, phoebus is currently using epics-pvaccess-5.1.1.jar, and runs into the error shown below.
Is that a matter of updating to the 'latest'?

Thanks,
-Kay

Hi all,

With some more investigation the issue turned out to be related to the
missing PVA security features. CAS has a function ca_write_access() ...
