I recently upgraded from Confluence Server 7.0.0 to 7.5.0, and I noticed these new variables in the setenv.sh:
-XX:+IgnoreUnrecognizedVMOptions
Xlog:gc+age=debug:file=$LOGBASEABS/logs/gc
-Djava.locale.providers=JRE,SPI,CLDR ${CATALINA_OPTS}
Could someone elaborate on what these variables do and why they were added?
