[android-developers] Why does Long.decode fail?

I am trying to convert a string of 16 hex digits to a 64-bit Long, but
there is a run-time exception for negative values:

Long a = Long.decode("0x3774d56d682e549c"); //..works just fine

Long a = Long.decode("0x9774d56d682e549c"); //..crashes with a run-
time exception

Apparently you can't decode a hex string that is negative as a 64-bit
Long. Why?
