Comment 1 Tomas Hurka 2014-12-19 09:36:01 UTC 
This is JDK 9 only issue caused by fix of JDK-8049367 (http://hg.openjdk.java.net/jdk9/dev/hotspot/rev/1d29b13e8a51). This fix removed system properties java.ext.dirs and java.endorsed.dirs. They are no longer set by JVM. :-(
Comment 2 Tomas Hurka 2014-12-19 10:25:12 UTC 
Fixed in profiler-main

Comment 4 Jiri Skrivanek 2015-02-20 07:10:41 UTC 
Verified. The following scenario works in dev build:

- create and build sample Anagram project
- run project from command line with JDK 1.9.0-ea-b50

D:\jdk1.9.0\bin>java -jar "D:\AnagramGame\dist\anagrams.jar"

- attach profiler to external process (Methods selected)
On the other hand when Objects are selected there is nothing in live results. I don't know if this is supported.
Comment 5 Marian Mirilovic 2015-02-24 13:47:57 UTC 
This is a candidate for NB 8.0.2 Patch 1 , so please integrate the bugfix into releases/release801 branch today by 10pm CET, for more information see
