Comments
From the initial run it seems that the default Java associated with jnlp is always 32-bit, when a 64-bit version, even if latest is installed along. Checked this on a Windows 10 system: Installed JRE 8u71 (32-bit) and 8u131/8u144 (64-bit). The JRE registered in the registry is always C:\Program Files (x86)\Java\jre1.8.0_71\bin\javaws.exe" "%1" Post removal of 8u71 (32-bit), correct JNLP association is regained. "C:\Program Files\Java\jre1.8.0_144\bin\javaws.exe" "%1" 9 ea b181, behaved fine as expected. The concern here is: - 64-bit Java installation is not setting correct JNLP association, when a lower 32-bit version is present. - An older version (8u71), supersede the JNLP association, even when the latest version is available.
