Product Version: NetBeans IDE Dev (Build 201401090002) Java: 1.8.0-ea; Java HotSpot(TM) 64-Bit Server VM 25.0-b65 Runtime: Java(TM) SE Runtime Environment 1.8.0-ea-b122 System: Linux version 3.5.0-45-generic running on amd64; UTF-8; en_US (nb) Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=384m; support was removed in 8.0 Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=32m; support was removed in 8.0
The warnings in log are harmless and effectively the change with JDK8 means that the previous permgen area has been replaced with the use of native memory inside JVM and the use is limited only by the amount of user's native memory. http://mail.openjdk.java.net/pipermail/hotspot-dev/2012-September/006679.html
Removing these switches (i.e. -XX:PermSize=32m, -XX:MaxPermSize=384m) is too complex and might be risky if running IDE on JDK 7 without these switches, in a case of wrong detection of JDK 7 in netbeans launcher. The switches will be removed when IDE runs of JDK 8 or newer only.
