  • *Bug Description* I failed to start up the Confluence 5.8.10 standalone with JRE1.8.0_60 on my machine, though I tried all the solutions that shown on Internet. On last resort, I downloaded the .bin instead just to see if it's working. Turns out that the .bin file includes JRE 1.8.0_51 which works fine. {code} 14-Sep-2015 14:43:34.676 INFO [main] org.apache.catalina.core.StandardService.startInternal Starting service
