The Launch-Time JRE Version Selection also known as Multiple JRE or mJRE functionality will no longer be available with the java launcher. This means the java launcher will not invoke another JRE version, and will exit with an error. The presence of "-version:x.y.z", "-jre-restrict-search" and "-jre-no-restrict-search" on the java launcher's command-line will cause it to exit with an error message. The environment variable "JRE_VERSION_PATH" will be ignored. The Java Archive (jar) manifest entry "JRE-version" will cause the java launcher to emit a warning, and "JRE-Restrict-Search" will be ignored.
