It should be ok anyway in the same VM. Unfortunately I had conflicting messages
on weather it's the name or the ordinal that is guaranteed to work across the
VMs :(.

Fascinating. Happily, as it turns out, we never compare these things
directly; instead, we extract a value from the enums and use that. The
value is populated in the enum constructor:
public enum IsolationLevel {
DEFAULT(-1),
NONE(Connection.TRANSACTION_NONE),
READ_UNCOMMITTED(Connection.TRANSACTION_READ_UNCOMMITTED),
READ_COMMITTED(Connection.TRANSACTION_READ_COMMITTED),
REPEATABLE_READ(Connection.TRANSACTION_REPEATABLE_READ),
SERIALIZABLE(Connection.TRANSACTION_SERIALIZABLE);
private final int _connectionConstant;
private IsolationLevel(int connectionConstant) {
_connectionConstant = connectionConstant;
}
protected int getConnectionConstant() {
return _connectionConstant;
}
}
Do you know if the getConnectionConstant() method would return the same
value for different instances of the "same" module?
