If you get the error:

ERROR context.GrailsContextLoader  – Error executing bootstraps: null

Message: null

while trying to save something in grails 2, go ahead and make use of the nice: failOnError option the save method gives you (http://grails.org/doc/2.0.x/ref/Domain%20Classes/save.html).

It will produce a much better output regarding what is wrong, in my case it showed me that i forgot to set a needed variable in my class before i tried to save it.

A nice guy in the mailing list pinpointed me to this one (http://grails.1312388.n4.nabble.com/Error-executing-bootstraps-null-with-springsecurity-plugin-td4554560.html).
