Could not generate cloud endpoints

[GoogleCodeExporter]

I'm working on a backend for my android app on google appengine from months up 
to now. Everything was working quite good until yesterday. 
I have not generated endpoint in last 2 months but when I tried to do so 
yesterday the error showed up.

What steps will reproduce the problem?
1. From Android IDE (Eclipse 4.2) I click on 'Generate cloud endpoint client 
library'.
2. ... I have to wait a BIG amount of time...
3. The error appear (I will paste the stacktrace below).

What is the expected output? What do you see instead?
Expected output -> all ok and my new endpoint library in my android project.
Actual output -> (stacktrace below).

What version of the product are you using? On what operating system?
Ubuntu 13.04 64bit.
AppengineSDK (tried 1.9.2 ,1.9.3, 1.9.4 )

Please provide any additional information below.

The problem was in my Code: a Blob passed as parameter.
Hard to find because eclipse did not give any clue about the issue, nor the 
output using endpoint.sh directly from appengine sdk.
