>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: io, native
>    Affects Versions: 1.0.2, 0.24.0
>            Reporter: Todd Lipcon

> SnappyDecompressor.c has the following code in a few places:
> {code}
>     THROW(env, "Ljava/lang/InternalError", "Could not decompress data. Buffer length is too small.");
> {code}
> 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.
