Deployer 6.5 Error

I am using Deployer since the beginning and I had only small issues. I think this is a very good tool.

But last week I updated an IS to 6.5 SP 1 (IS_Build395Update.jar) with SAP Adapter 6.5.

Since then I am not able to deploy any package to that IS with the error:

java.nio.BufferOverflowException at java.nio.charset.CoderResult.throwException

The IS where I run the deployer is with IS 6.5 SP1.

Any ideia ?
