Installing NetBeans 8.0.1/8.0.2 on MacOS X 10.10 with JDK 8/9 installed results in having an immediate crash during app run startup due to: Unrecognized VM option 'PermSize=32m' Error: Could not create the Java Virtual Machine. PermGen is obviously unsupported on Java 8/9, and the PermSize switch has been removed from them (see e.g. http://stackoverflow.com/questions/18339707/permgen-elimination-in-jdk-8 for more information), resulting in JVM startup error. Removing the offending switch from netbeans.conf JVM switches makes the application running perfectly.
BTW, by "netbeans.conf JVM switches" I obviously mean "netbeans_default_options" entry in conf.
