Using gateway-mq profile in Fuse 6.1 with JDK 1.6 gives error: java.lang.UnsupportedClassVersionError: org/vertx/java/core/Handler : Unsupported major.minor version 51.0

Issue

When the profile gateway-mq is assigned to a managed container when using Fuse 6.1 or earlier, under JDK 1.6, the container fails to start, and this error message is seen in the log:

error: java.lang.UnsupportedClassVersionError: org/vertx/java/core/Handler : Unsupported major.minor version 51.0

It is likely that the same problem will be noticed with other profiles that depend on the vert.x event-based programming platform.

Environment

JBoss Fuse 6.1 or earlier
