"Association ConcurrentModificationException"

bahadigo

Hi Guys,

i have a RapidMiner acadamia license and installed the RapidMiner Studio 6.5.002 on a Windows Server 2012 R2 Standard. I am the only user who connect to the windows server using remote desktop. I have a dataset with 60000 rows and 130 binominal attributes. Now when i start the Fp-Growth- and create-Association-Rule -Operator i get the following error:

Exception: java.util.ConcurrentModificationException
Message: null
Stack trace:

Could anyone help me figure out as to why this problem is occuring and how to solve it?

The Error Message reads:
