There are many similar issues discussed on the Lucene developer's mailing list, it's an interesting read: - http://mail-archives.apache.org/mod_mbox/lucene-dev/201503.mbox/%3C07c401... I see no alternative than to have those test jobs actually exercising ORM with JDK6, or maybe even compile it all with JDK6 except the Java8 additional module to be compiled with JDK8 ?
