title: How to read and understand a monster exception (for example this one)
body: <p>We are currently facing the problem that somewhere in our application a monstrous exception is generated. Since we are using Grails and the Spring Framework, the Exception is thrown somewhere in there.</p>
  
  <p>There seems to be some endless loop, and the Exception Stack is getting longer and longer, everytime it is thrown again. I have no clue what in our code could have caused this, and I assume that it is just one of the usual misconfigurations or small errors, that sometimes make Grails fail dramatically.</p>
  
  <p>I will try to outline the major parts of the exception here, but since a thrown exception uses 2 GB in the log, i can only show parts. Even vi is having trouble opening it, and it seems to be thrown until the Hard Disk memory is full.</p>
  
  <p>First Line</p>
