Hi, Mark and Tomasz!

With ij.jar at /usr/share/java/ij.jar and the master branch of
ADViewers, this should work:

----
$ cd ADViewers/ImageJ/EPICS_areaDetector
$ ij_jar=/usr/share/java/ij.jar
$ javac -cp ".:jna-5.1.0.jar:epics-ntypes-0.3.5.jar:epics-pvaccess-5.1.5.jar:epics-pvaclient-4.3.2.jar:epics-pvdata-6.1.5.jar:$ij_jar" ByteBufferUtil.java NTNDCodec.java EPICS_NTNDA_Viewer.java
----
