Starent radius packet attribute length is 2 byte. While testing with decoding and encoding starent radius attribute, tinyradius was going infinite loop during decoding and failed to encode in case length more than 255. With this changes it now handles starent radius dictionary.

The library has also been tested well with starent radius dictionary (2 byte attribute length).

I'd prefer you remove the commented out code, not sure what is the purpose to leave it as commented out.

Why checking for -1?

attr[2] = (byte) (data_length >> 8 & 0x0ff);
attr[3] = (byte) (data_length & 0x0ff);
System.arraycopy(attributeData, 0, attr, 4, attributeData.length);
return attr;

I would like to see a unit test to verify previous and modified behavior?
