--------------------------------------------------
Key: HIVEMIND-76
URL: http://nagoya.apache.org/jira/browse/HIVEMIND-76
Project: HiveMind
Type: Bug
Components: framework
Versions: 1.0, 1.1
Reporter: Howard M. Lewis Ship
Assigned to: Howard M. Lewis Ship
Fix For: 1.1
For certain complex interfaces, HiveMind gets runtime errors generating a class:

Exception in thread "main"
Investigation found that the interface in question,
kodo.runtime.KodoPersistenceManager extended a number of other interfaces,
and has conflicting definitions for method close():
void close() throws Exception ... from com.solarmetric.util.Closeable
void close() throws javax.resource.ResourceException ... from
javax.resource.cci.Connection
void close() ... from javax.jdo.PersistenceManager
HiveMind was attempting to implement all of these, causing problems (same
return type, same name, same parameters means there can be only one such
method).
HiveMind needs to more carefully analyze these method signatures and implement
the most general case; in this case "void close() throws Exception". This
logic is centralized in the MethodIterator and MethodSignature classes.
