This same problem breaks RIFE compatibility in the 3.0.20 release. 3.0.19 works fine.

The stacktrace is slightly different:

     [java] Caused by: com.caucho.hessian.io.HessianProtocolException: expected hessian method ('m') at code=99 ch=c
     [java] at com.caucho.hessian.io.HessianInput.error(HessianInput.java:1642)

Running against the Hessian jar created by the 3.1 distribution produces the same error, but with a slightly different stack trace:

     [java] Caused by: com.caucho.hessian.io.HessianProtocolException: expected hessian method ('m') at code=99 ch=c
     [java] at com.caucho.hessian.io.HessianInput.error(HessianInput.java:1647)

hessian/3550.

Made changes for backwards compatibility. The HessianSkeleton.invoke is now expected to be called after the 'c' x02 x00 is read so the parent caller can choose between Hessian2 and Hessian1. The fix allows the old-style invoke callers to still work.
