Re: EmptyStackException in Log4j2 beta5 and beta6
I will try to verify this fix in the next couple of days. $Work today, Stark Trek premier tonight... FYI, here are some Java links: - Latest binaries and link to archives: https://jdk8.java.net/download.html - API Documentation: http://download.java.net/jdk8/docs/api/ - Milestones: http://openjdk.java.net/projects/jdk8/milestones - Source code: http://hg.openjdk.java.net/jdk8/jdk8/jdk/, http://hg.openjdk.java.net/jdk8/jdk8/hotspot/, http://hg.openjdk.java.net/jdk8/jdk8/langtools/ - Source for sun.reflect.Reflection (look at the revision history and you'll see why the change was made): http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/b8e7d145abc2/src/share/classes/sun/reflect/Reflection.java, http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/b8e7d145abc2/src/share/native/sun/reflect/Reflection.c Rampdown starts in July. API Freeze is in October. If there's going to be a replacement for this, it will definitely happened before API Freeze, but my bet is before Rampdown. My suggestion on the mailing list is a better replacement for our needs, though: http://mail.openjdk.java.net/pipermail/java-se-8-spec-comments/2013-May/14.html Nick On May 15, 2013, at 11:29 AM, Ralph Goers wrote: Nick, Have you verified the fix I made to avoid the exception below?
