It is not possible to remove Datasource with double slashes in its JNDI  - e.g. "java://test". The operation will fail with the error below:

/subsystem=datasources/data-source=test:remove()
{
    "outcome" => "failed",
    "failure-description" => "JBAS014749: Operation handler failed: Empty name segment is not allowed for java",
    "rolled-back" => true
}


How to reproduce
1) create a new datasource with JNDI "java://test"
2) try to remove DS create in previous spec

Expected result: DS is removed
Actual result: Error
