Got the following error, probably some parsing inconsistency, cause this came back from coturn stun

Could you please share the input data? It looks like the input data is malformed!

Hi, this is the data returned in hex that is causing the issue -
Data : 01110070f4a21402935aef2941f7426af83c01ab0009004c00000414556e6b6e6f776e206174747269627574653a205455524e207365727665722077617320636f6e6669677572656420776974686f757420524643203537383020737570706f727400008022001c436f7475726e2d342e352e32202764616e20456964657227000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
arraycopy: last destination index 24 out of bounds for byte[20]

this is the place in the code where I added the print - (if fails in the parseAttributes)

Thanks for sharing the hex data. It looks malformed to me. How do you see it (what does Wireshark tell you)?

o.k., it seems like it is a problem within the code.
I tried also this one : stun.f.haeder.net (port 3478)
There is a problem in parsing the result
Very same error there.
