Java has bug again. After you installed idk 1.8u25 in your mac, open Eclipse.app/Contents/MacOS/eclipse.ini, you will see: -vm /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home But actually this line has no effect, when you run eclipse with -console -debug, you still see it is running use idk 1.6 “-vm /System/Library/Frameworks/JavaVM.framework”. To fix it, change that line to -vm /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java Peter. 2014/12/22
