Cause
This is due to a change in behaviour of caching with Java after 8u202, In this version and above Java performs a HTTP HEAD instead of HTTP GET on the Java JAR file. TPAM did not support the HTTP HEAD.
From Java change log:"➜ Changes in Update Process of Java Web Start Cached ObjectsThe update mechanism of cached Java Web Start objects has been slightly changed. Now Java Web Start issues HTTP HEAD request instead of GET to test whether the updates for cached object are available or not. The downloading of the updates did not change and keeps working in the same way as before." -
