title: StackOverflowError, can't find where in my code I made the call
body: <p>I have a StackOverflowError in Java and it doesn't tell me any line in my own code, the relevant part of the stacktrace is:</p>
  
  <pre><code>java.lang.StringBuilder.append(StringBuilder.java:132)
  java.util.AbstractMap.toString(AbstractMap.java:523)
  java.lang.String.valueOf(String.java:2838)
  java.lang.StringBuilder.append(StringBuilder.java:132)
  java.util.AbstractCollection.toString(AbstractCollection.java:439)
  java.lang.String.valueOf(String.java:2838)
  </code></pre>
  
  <p>I've tried getting the stack trace from the throwable, but for some reason it doesn't contain the relevant nodes, I'm trying to find some inpoint in my code as to where the error is.  Also I've tried to reduce the stack size to 128k to get the error earlier, no avail.</p>
