Hi Mark,

The updated ADViewers/ImageJ/EPICS_areaDetector works properly with debian imagej package and default Java 11 on

Ubuntu 20.04
Debian 10

I am not sure where epics-pvaclient-4.3.2.jar comes from.

Thanks for this upgrade of ImageJ ADViewer.

Hi Kaz,

I have updated the .jar files in ADViewers/ImageJ/EPICS_areaDetector on Github as follows:

caj-1.1.10.jar Deleted, not needed.

epics-ntypes-0.3.5.jar Updated from 0.3.1

epics-pvaccess-5.1.5.jar Updated from 5.1.1

epics-pvdata-6.1.5.jar Updated from 6.1.1

epics-pvdatabase-4.3.1.jar Deleted, not needed

epics-util-1.0.3.jar New file, needed by new version of pvAccess

jca-2.4.5.jar Updated from 2.3.6

I have tested on Centos 7 and Windows 10 using a fresh ImageJ/plugins/EPICS_areaDetector from the master branch ADViewers. Both the EPICS_AD_Viewer (Channel Access) and the EPICS_NTNDA_Viewer (pvAccess) work fine using the latest ImageJ (1.53d) and the jre that comes with that.

Kaz, please test to see if the master branch works with your Java 11 system. The dependency on Corba should be gone, so it should work.

Answers to your questions:

Ø epics-pvaclient-4.3.2.jar {Source location}

Source location is https://github.com/epics-base/pvaClientJava. However, unlike epicsCoreJava the .tar.gz files for pvaClientJava do not include .jar files.

Ø jna-5.1.0.jar {What is this}

This is Java Native Access. https://github.com/java-native-access/jna. It is used to call the decompression codecs (JPEG, Blosc, bitshuffle, etc.) from ImageJ for compressed NTNDArrays.

Ø NetCDF_.jar {Source location}

Source location is https://lmb.informatik.uni-freiburg.de/resources/opensource/imagej_plugins/netcdf.html.

Mark,

The .jar files in current ADViewer distribution:

caj-1.1.10.jar
epics-ntypes-0.3.1.jar
epics-pvaccess-5.1.1.jar
epics-pvaclient-4.3.2.jar
epics-pvdata-6.1.1.jar
epics-pvdatabase-4.3.1.jar
jca-2.3.6.jar
jna-5.1.0.jar
NetCDF_.jar

I am not sure where sources for

· epics-pvaclient-4.3.2.jar {Source location}

· jna-5.1.0.jar {What is this}

· NetCDF_.jar {Source location}

Is epics-pvdatabase-4.3.1.jar needed?

Remaining most recent .jar files are distributed. The jca and caj is combined into jca, I think.

Kaz

It appears that the CORBA dependency in pvAccess was removed in this commit in June 2018.

https://github.com/epics-base/epicsCoreJava/commit/1d300d365c91b7fdc89bb93ee4d7b4b3241c734a#diff-91dff54d9f3689d9045dbd98eea6b1f2

I will work on updating ADViewers to use the most recent pvAccess jar files.

Mark

Where's the source code for the epics-pvaccess-5.1.1.jar? Is it the following?

https://github.com/epics-rip/pvAccessJava/tree/5.1.1

If so, that code contains three classes that reference classes in the org.omg.CORBA package that have been removed in Java 11:

src/org/epics/pvaccess/impl/remote/IntrospectionRegistry.java
src/org/epics/pvaccess/util/IntHashMap.java
src/org/epics/pvaccess/util/ShortHashMap.java

I don't know anything about pvAccessJava, but if the latest version is at

https://github.com/epics-base/epicsCoreJava

then a search for "corba" there shows that it does not contain references to classes in the org.omg.CORBA package, so if you can upgrade to a newer version of pvAccessJava that does not reference CORBA classes, then I think the problem would go away.

Another solution would be to add JARs to the Java classpath providing the CORBA classes such as from JacORB:

https://github.com/JacORB/JacORB

Yet another solution would of course be to use a Java 8 VM instead of a Java 11 VM.
