Subject RE: [HUDSON] Lucene-trunk - Build # 1523 - Failure
Date Fri, 08 Apr 2011 21:26:42 GMT
AFAICT, these (Oracle/Sun-only) JVM parameters were introduced in 1.6 (that's what this parameters
list says: http://blogs.sun.com/watt/resource/jvm-options-list.html) - we tell Jenkins to
use 1.6 for Lucene/Solr testing, so this isn't an issue in practice, I guess.

Hopefully 1.5 JVMs, and non-Oracle/Sun JVMs, won't choke on these unknown parameters.
