Thanks to the Team at Lynxspring we know:
Dear Lynxspring Technology and Business Partners
As previously communicated, Oracle announced the pending end-of-life of Java SE 8 (Standard Edition). As a result, as of January 2019, free public updates are no longer available. Customers accessing Niagara with the Java Applet/Web Start are impacted by this change. Those who have upgraded to full HTML5 versions for their browser front-end will not be affected. For customers who use the Java VM and Java Web Start for their legacy systems, Tridium is actively developing a suitable alternative that we are expecting to receive soon and will share with you ASAP.
UPDATE: Starting with the April 2019, scheduled quarterly critical patch update from Oracle, Commercial Users will have access to updates through My Oracle Support for their Java Applet/Web Start. Or users can begin utilizing the Niagara alternative, Niagara Web Launcher, which is currently scheduled to be available in mid-March.
Please review this video to get a better understanding of what to expect.
To assist in understanding the potential impact to your system, please review the FAQ section below.
