By Java documentation, java.endorsed.dirs is used to provide an Endorsed Standards Override Mechanism. Which means, a user can provide newer versions of certain packages than those provided by the JDK. If there are newer implementations of these packages in the directories specified by java.endorsed.dirs, those implementations will be loaded instead of the default ones that come with the JDK.
The packages that can be overriden this way are grouped into Endorsed Standards APIs and Standalone Technologies, and are listed in the Java documentation.
Roughly speaking the Endorsed Standards APIs include:
Standalone Technologies include:
