[Netarchivesuite-devel] java.lang.UnsupportedClassVersionError when deploying 3.18

[Nicolas Giraud]

Hi Søren,

I actually found out the problem. I installed JDK 1.7.0 a while ago for
evaluation, and my Ant build would, for some reason, use this JDK instead
of the default 1.6.x configured for the Eclipse workspace. Has to go
through the "External tools configuration" setup menu to force Ant to use
the same JRE as the project.

It works now, sorry for the hasty posting...
