As far as I know we're not using any ArrayLists in the SDK so that error looks like it's something coming from your app.

[pablisco]

MutableList (subscriptions in this case: ChatManager:160) is actually an ArrayList when it gets compiled. That said, there is no possible way that calling the add (or plus-equals) function can cause that. The line in question has a += operator that is translated into an add method call: MutableCollections:64

The add method in ArrayList doesn't throw such exception: ArrayList#add. Is that the complete stacktrace? Also, the line the trace mentions is a comment on this version, what version of the JVM are you using?
