JRE 1.8.0_241 32-bit SSV Helper Add-On causes long load time in 32 bit IE11 launch on Windows 10 v1809.

Whenever IE is started, "ssvagen.exe -old" process is seen in Task Manager; opening new tabs in IE results in another "ssvagen.exe -old" process. Manage Add-ons reports load times of SSV Helper are over 1 minute.
Root Cause: For some reason in this particular environment, Java Plugin SSV Helper components cannot open the registry key: HKLM\SOFTWARE\WOW6432Node\JavaSoft. Because of the failure, the components cannot read the value UseNewJavaPlugin from the registry and default to behaviour as if the old Java plugin is selected. In this case, ssv.dll tries to fix up the implementation of all Java Plug-in GUIDs from jp2iexp.dll to ssv.dll. So it starts the helper process "ssvagent.exe -old" but for Java 8 and above, the "-old" option is treated as "-new", and ssvagent.exe writes jp2iexp.dll as expected for the new plugin. The registry entries remain the same. When IE accesses SSV Helper object once again, it results in another fix-up attempt. It does not affect Java Plug-in itself but IE is slow to open new tabs and load pages. The Fix: Make SSV Helper objects to always default to the new plugin.
