ConcurrentModificationException when pasting multiple objects copied from a different report

[powermacx]

If I copy a large number of objects in iReport from one report to another, I get a ConcurrentModificationException when pasting and several of the copied objects fail to be pasted. I made a very simple test case that reproduces the problem: blank report made from the blank A4 template, in which I created 25 "Static Text" objects.

Steps to reproduce:

- Create a new blank document (from the blank A4 template)

- Open the attached test report, select all 25 static text objects and select copy

- Switch to the blank document and select paste

Result:

 java.util.ConcurrentModificationException

This is with iReport 3.7.6.
