Akka 2.2.3 -> 2.3.2

[Alanlit]

Hello fellow hAkkers,

I have a series of modules that communicate via Akka -- was version 2.2.3 and all was fine. Upgraded to 2.3.2 and three of the four modules (which share their initialization code - just different configs) are fine but the third always gives:

Simply switching back to 2.2.3 fixes everything.  Using maven to build and I see the different protocol buffer versions being pulled in between versions ..... the really head banging thing as I say is it only fails in one module, and so much of the code leading up to Akk initialization is common ..... anyone have any insights ??

Tnx

For what it is worth the problem exists (in the the one module) for Akka 2.3.1, 2.3.2 and 2.3.3. Switching back to the 2.2 branch (.3 or .4) and all works just fine. Sadly other external factors are mandating a shift to 2.3.x ...

Again, the above error happens during Akka ActorSystem initialization, so it is a little hard for me to construct a scenario to explain this ...

Could you try to minimize this to a reproducible example?

Verify that you have protobuf version 2.5.0 in your classpath.

Good call !!  I found that a third party library has (of course) an old version of protobuf tucked inside it. Removing that for now fixed everything.

Great! You're welcome.

Just a warning (because I went this route before you) that proto files
compiled to java with protobuf 2.4.1 are not compatible with the
protobuf 2.5.0 runtime library.

In my case our own application is very dependent on protobuf and I had
to recompile some of our dependencies that were using protobuf compiled
files with 2.4.1.
