camel-sql missing spring-tx does not allow using Idempotent Routes in Fuse on EAP

Issue

• We tried to create a JDBC based idempotent consumer, and it's deployment fails with a ClassNotFoundException for org/springframework/transaction/support/TransactionCallback.
  Packaging the dependency in the app by adding org.springframework.tx does not help.

• This jar is also available as a module in FUSE_HOME/system/layers/fuse/org/springframework/tx, though it's declared as private. So we tried to set an explicit dependency using both the MANIFEST.MF method and the jboss-deployment-structure.xml method https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.4/html/Development_Guide/Add_an_Explicit_Module_Dependency_to_a_Deployment1.html.

• They seem to take effect, as we get a WARN message about using a private API

(WARN  [org.jboss.as.dependency.private] (MSC service thread 1-2) JBAS015867: Deployment "deployment.idempotent-0.0.1.war" is using a private module ("org.springframework.tx:main") which may be changed or removed in future versions without notice.), but the deployment still errors out with the stack trace pasted below.
