Solr 4.10.x on Oracle Java 1.8.x ?

Hi guys,

at the end of April Java 1.7 will be obsoleted, and Oracle will stop 
updating it.

Is it safe to run Tomcat7 / Solr 4.10 on Java 1.8? Did anyone tried it 
already?

We have several issues with Java 8. They are mostly with using DIH handler,
since we use the script Nashorn, and it was originally Rhino.

When using Regex, we needed to escape "\\|" in Rhino and in Nashorn we need
to use only 1 escape "\|".

Several other issues since methods on Java String appear to call the
Nashorn String functions (like MyString.split('\\|'))....

Be careful and test it.

Yes, we know that Java 8 works just fine with newer Solr 4.x releases,
and the unreleased version 5.  Oracle Java is preferred, and the latest
available release is strongly recommended.

The development branch for Lucene/Solr 6.0 *requires* Java 8.

Thanks,
Shawn

Bok Jakov,

We've been running Solr with Java 8 for several months without issues.
