invoke() for "listFormattedSubPoolStatistics" ManagedOperation on datasources and connection factory ManagedComponents returns a MetaValue with the wrong MetaType

This is another case of the data not matching the metadata.

operation.getReturnType() returns a MutableCompositeMetaType w/ typeName java.lang.Object. However, invoke() is returning a SimpleMetaType.STRING (with value e.g. "Sub Pool Statistics: \nSub Pool Count: 0\n------------------------------------------------------\n").
