  1. Stop the instance
  2. Delete all file starting with history <cq_home>/logs/history*
  3. Start the instance & verify.
  4. This could happen if you have special character in dam asset file name like $..

Try removing the recently installed packlages and see if that works. SOmething has caused an issue. I  am thinking it was code in a package.

AEM 6 is a stable version with SP2, as stated by scott the packages that were installed after SP2 might have caused this issue.

This issue might occur if you have tried uninstalling SP2, as it will corrupt your instance.

Note:- SP2 once installed cannot be uninstalled, you have to setup a fresh instance.

Exactly, what Sham Said.

Please have a look at this link:-

Link:- http://bloggershetty.blogspot.in/2006/10/java-string-replace-javalangindexoutofb.html

//  java.lang.IndexOutOfBoundsException: No group 2

Reason:- You possibly have "$" character in your target string.

Also check if you have used some string replacing or string manipulation function in recent service/component. Try removing the OSGI service/component added from "\crx-quickstart\launchpad\installer"
