I see what you mean and I know what the problem is. :-) This is what happens: * TM is ready to be undeployed * list (X) of all deployers for Real is prepared * BeanMDDeployer for TM kicks in --> unwinding your JDBC deployer * your JDBC deployer is still used since it was part of X list Either move your JDBC deployer to diff deployment stage, or somehow move it before BMDDeployer on undeployment.
