Description

SnappyDecompressor.c has the following code in a few places:

    THROW(env, "Ljava/lang/InternalError", "Could not decompress data. Buffer length is too small.");

this is incorrect, though, since the THROW macro doesn't need the "L" before the class name. This results in a ClassNotFoundException for Ljava.lang.InternalError being thrown, instead of the intended exception.
