Re: ACE 1.8 requires JDK 1.7?

[shake]

Hi,

Yes, it requires Java 1.7. I'll go through our wiki and update the pages which list dependencies to reflect this change.

SEVERE: Skipped installing application listeners due to previous error(s)

From the "Unsupported major.minor version 51.0 (unable to load class edu.umiacs.ace.ims.ws.TokenResponse)", it looks as though the classes have been compiled against 1.7, though the requirements indicate 1.6 (https://wiki.umiacs.umd.edu/adapt/index.php/Ace:Audit_Manager_Installation_Guide). Has this changed? If not, can the classes be recompiled against 1.6?
