 Used to use an over-engineered "plugin" mechanism although there was only one
 "plugin", called "sunmajor", that handles all possible JREs.

+IMPORTANT:  The <updated> element in 
vmfwk/distributions/OpenOfficeorg/javavendors_*.xml files
+should only be updated for incompatible changes, not for compatible ones.  As 
stated in the commit
+message of <https://gerrit.libreoffice.org/#/c/69730/> "javavendors_*.xml 
<updated> should not have
+been updated...":  "Changing <updated> causes jfw_startVM and 
jfw_getSelectedJRE (both
+jvmfwk/source/framework.cxx) to fail with JFW_E_INVALID_SETTINGS, which in 
turn causes functionality
+that requires a JVM to issue a GUI error dialog stating that the user must 
select a new JRE in the
+Options dialog.  While that behavior makes sense if a JRE was selected that 
would no longer be
+supported by the modified javavendors_*.xml, it is just annoying if an already 
selected JRE is still
+supported.  And a compatible change to javavendors_*.xml implies that an 
already selected JRE will
+still be supported."
