Some JNDI names prevent disabling datasources

It seems that certain JNDI names cause errors:

14:25:22,365 WARN [org.jboss.as.controller] (HttpManagementService-threads - 2) Operation ("disable") failed - address: ([
("subsystem" => "datasources"),
("data-source" => "mysql")
]): org.jboss.as.controller.OperationFailedException [ "Data-source service [mysql] is not available" ]

The datasource in question has a JNDI name with slash:
[standalone@localhost:9999 /] /subsystem=datasources/data-source=mysql2:read-attribute(name=jndi-name)
{
"outcome" => "success",
"result" => "jdbc/mysql2"
}

[standalone@localhost:9999 /] /subsystem=datasources/data-source=mysql2:disable
{
"outcome" => "failed",
"failure-description" => "Data-source service [mysql2] is not available",
"rolled-back" => true
}
