Release 3.16.0 includes a number of fixes to make
compatible with newer Java revisions
(it remains to be backward compatible with Java 1.7+).
Addressed several incompatibilities with newer Java versions,
both at build-level and at runtime. Workbench now works with
Workbench bug fixes and workarounds for newer Ubuntu releases,
odd characters in installation path and Java 1.9 compatibility.
Updates ETools document source URLs to use HTTPS. Removed Indeed
document source (no longer functional)
Added a constructor for the Document class that takes an external ID,
making it consistent with Java API Document class.
