Subject RE: JDK-8 developer preview for our Jenkins?
Date Mon, 11 Nov 2013 22:23:43 GMT
Hi,

Cool! Oracle asked yesterday if they should ask other ASF projects, too, and they did :-)

At the moment we are doing the Lucene/Solr tests in close cooperation with Oracle (we had
some phone conferences the last weeks about this). Unfortunately we cannot run this on the
ASF Jenkins machine at the moment, because we use some custom groovy scripts inside Jenkins
to randomly choose a different JVM + full dynamic configuration (like garbage collector, bitness,
compressed oops, client/server VM, it’s a large number of combinations possible). By this
we already found tons of bugs in Java 8, but also the reason for the stability problems in
Java 7u40 and u45, so Oracle is happy to work together with the Lucene project.

The Jenkins server running all these tests is available at: http://jenkins.thetaphi.de
Here is the talk about this setup: http://berlinbuzzwords.de/sites/berlinbuzzwords.de/files/slides/Schindler-BugsBugsBugs.pdf
This machine is running Linux (Ubuntu 12.04) with 2 VirtualBOX VMs running Windows 7 and MacOSX
10.8 (natively, non-patched/cracked, non-hackintosh EFI64 setup)

Unfortunately, without support for this special configuration through ASF and/or additional
hardware, I cannot provide this service to other projects.

Uwe
