Hi, I am getting ConcurrentModificationException in StyleRenderer and I am not sure where is the problem.
I have several other problems related to my project, not sure if they are bugs, to share them here. I tried to register in the sympa, but did not find how to ask the question. Could I list them in the next issue?

I have several other problems related to my project, not sure if they are bugs, to share them here. I tried to register in the sympa, but did not find how to ask the question. Could I list them in the next issue?
