NullPointerException at NearestVersionConflictResolver.selectVersion()

Benjamin Bentmann added a comment - 07/Sep/10 8:23 AM Any chance of an example project?

Benjamin Bentmann added a comment - 07/Sep/10 10:41 AM I can't follow, same project from what? And what exactly is the relation to MNG-4794 that shows a completely different error output?

Jochen Stiepel added a comment - 07/Sep/10 3:10 PM Sorry, for my short comment. If I run mvn clean install I'll get MNG-4794 If I run mvn clean package I'll get MNG-4798 (this issue) It is the same maven multiproject from within I call maven. It ONLY happens with Maven 3 Beta-3 and NOT with Beta-2. It ONLY happens on my Linux Server and not on my Windows Notebook. (Same Java Version). I don't have an example project currently. What else can I do for you? Providing debug output? I thought, maybe my Maven 3 Beta-3 installation (from tar.gz) is broken, but I'll get the same error from another installtion out of the zip-archive. What else can be plattform specific? Or can be corrupt on my Linux-Server? I'll try to run it on another Linux-Installation to check it there.

Benjamin Bentmann added a comment - 07/Sep/10 3:19 PM What else can I do for you? Providing debug output? Yes, that's always a help as it gives some more context. In particular, if MNG-4794 is reproducible for you, I would like to see the debug from a failing "mvn clean install" against an empty local repo (or at least one, where the maven-install-plugin has been completely deleted).

Jochen Stiepel added a comment - 08/Sep/10 8:03 AM I found the cause of this problem! On the SLES Server there were two JDK's installed. The Sun JDK and an IBM JDK. JAVA_HOME was pointing to the IBM-JDK and in the PATH the Sun JDK was first: output of: mvn -version Apache Maven 3.0-beta-3 (r990787; 2010-08-30 14:44:03+0200) Java version: 1.6.0 Java home: /usr/lib/jvm/java-1_6_0-ibm-1.6.0/jre Default locale: de_DE, platform encoding: ISO-8859-1 OS name: "linux" version: "2.6.27.48-0.6-pae" arch: "x86" Family: "unix" output of (Sun JDK): java -version java version "1.6.0_21" Java(TM) SE Runtime Environment (build 1.6.0_21-b06) Java HotSpot(TM) Client VM (build 17.0-b16, mixed mode, sharing) output of (IBM-JDK): /usr/lib/jvm/java-1_6_0-ibm-1.6.0/jre/java -version java version "1.6.0" Java(TM) SE Runtime Environment (build pxi3260sr8-20100409_01(SR8)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260sr8-20100401_55940 (JIT enabled, AOT enabled) J9VM - 20100401_055940 JIT - r9_20100401_15339 GC - 20100308_AA) JCL - 20100408_01 Then I changed the JAVA_HOME to the Sun-JDK and it works. Afterwards I changed the JAVA_HOME and the PATH to the IBM-JDK and I'm getting the exception again.

Benjamin Bentmann added a comment - 09/Sep/10 4:09 AM Please fill this as a bug against the JDK vendor.

Benjamin Bentmann added a comment - 24/Sep/10 9:53 AM Stuart McCulloch debugged this and tracked it down to HARMONY-6419 which affects the ConflictMarker.mark() method from Aether.
