Todd Lipcon commented on HDFS-3643:
-----------------------------------
{code}
+ else {
+ jthr = newRuntimeError(env, "invokeMethod: invalid return type 0x%02x",
+ returnType);
+ }
{code}
Why is returnType being printed in hex here? Wouldn't it be a string which
comes from the signature? eg something like "Ljava/lang/String;" or "J"?

> This loop needs to check for {{'\0'}}. Also the following {{if/else if/else
> if}} cascade doesn't handle unexpected values.
