Hi, This was just an example - the one I have seen first. It also fails with a simple ManagementFactory.getRuntimeMXBean(). Or ManagementFactory.getGarbageCollectorMXBean(). Or ManagementFactory.getAnyOtherFooBarMXBean(): Same error - quite clear - a bug! The problematic code is the service loader that does not find the class which is listed in the JDK's internal META-INF/services.
Uwe P.S.: the HotspotMXBean is public (marked as @Exported and part of compact3 profile in Java 8): https://docs.oracle.com/javase/8/docs/jre/api/management/extension/com/sun/management/HotSpotDiagnosticMXBean.html And this is *not* Jigsaw. Was just standard build. But works with Jigsaw, build 109, too! ----- Uwe Schindler uschind...@apache.org ASF Member, Apache Lucene PMC / Committer Bremen, Germany http://lucene.apache.org/ > -----Original Message----- > From: Remi Forax [mailto:fo...@univ-mlv.fr] > Sent: Thursday, March 17, 2016 7:24 PM > To: Uwe Schindler <uschind...@apache.org> > Cc: Core-Libs-Dev <core-libs-dev@openjdk.java.net>; Rory O'Donnell > <rory.odonn...@oracle.com> > Subject: Re: JDK 9 build 109 -> Lucene's Ant build works again; still missing > Hotspot patches > > It's not a bug, it's a feature :) > com.sun.management.HotSpotDiagnosticMXBean is a com.sun classes, so > maybe not available anymore. > > see > https://wiki.openjdk.java.net/display/JDK8/Java+Dependency+Analysis+Too > l > > Rémi > > ----- Mail original ----- > > De: "Uwe Schindler" <uschind...@apache.org> > > À: "Core-Libs-Dev" <core-libs-dev@openjdk.java.net>, "Rory O'Donnell" > <rory.odonn...@oracle.com> > > Envoyé: Jeudi 17 Mars 2016 17:03:25 > > Objet: RE: JDK 9 build 109 -> Lucene's Ant build works again; still > > missing > Hotspot patches > > > > Hi, > > > > In fact, any static method on ManagementFactory fails with this trace.
