Getting SQLException on DB Login, but Report Runs?????

Question

On all of our JRC-enabled Crystal reports, I'm getting the same SQLException error thrown, however, the report runs OK in most cases.  In longer running reports, the user is getting weird JSF state exceptions, HTTP 500 errors, etc. etc.  When I look at the log files for our web app, the below error is showing constantly.  Any ideas what it means, please?

This error looks like it happens on every report run, but most times, the report runs fine.  In some cases they are getting other errors that may or may not be related to this one, very glitchy things like NullPointerExceptions, "Can't use a closed connection" messages, ArrayIndexOutOfBoundsExceptions, etc. and they are not consistent.  You run a given report 10 times, you might get these errors 2 of the 10.  When I used the non-JSF JRC implementation in other projects, it worked fine, so I'm not sure what I'm doing wrong with the JSF code.  Below is my database connection method if that helps:
public ConnectionInfos getDBConnection(){
        IConnectionInfo oIconnectionInfo = new ConnectionInfo();
        ConnectionInfos oConnectionInfos = new ConnectionInfos();
        FacesContext fc = FacesContext.getCurrentInstance();
        Map<String, Object> Params = (Map<String, Object>) fc.getExternalContext().getSessionMap();
try {
        ReportSelectionBean sBean = (ReportSelectionBean)Params.get(IManagedBeanNames.REPORT_SELECTION_BEAN);
        String driver = Configuration.getProperty("CrystalDBDriver");
        String ConnStr = null;
        String instance = Configuration.getProperty("db-schema");
        if (instance.equals("crca"))
            ConnStr = "Use JDBC=b(true);Connection URL=s(jdbc:oracle:thin:@pabaix10:1521:crca);Database Class Name=s(oracle.jdbc.OracleDriver);Server=s(pabaix10);User ID=s(crcuser);Password=crcuser1;Trusted_Connection=b(false);JDBC Connection String=s(!oracle.jdbc.OracleDriver!jdbc:oracle:thin:{userid}/@pabaix10:1521:crca)";
        } else if (instance.equals("crcp"))
            ConnStr = "Use JDBC=b(true);Connection URL=s(jdbc:oracle:thin:@pabaix08:1521:crcp);Database Class Name=s(oracle.jdbc.OracleDriver);Server=s(pabaix08);User ID=s(crcuser);Password=crcuser1;Trusted_Connection=b(false);JDBC Connection String=s(!oracle.jdbc.OracleDriver!jdbc:oracle:thin:{userid}/@pabaix08:1521:crcp)";
        PropertyBag propertyBag = new PropertyBag();
        if (instance.equals("crca"))
            propertyBag.put("Server Name", "pabaix10");
            propertyBag.put("URI", "!oracle.jdbc.OracleDriver!jdbc:oracle:thin:{userid}/@pabaix10:1521:crca");
            oIconnectionInfo.setUserName("crcuser");
            oIconnectionInfo.setPassword("crcuser1");
        } else if (instance.equals("crcp"))
            propertyBag.put("Server Name", "pabaix08");
            propertyBag.put("URI", "!oracle.jdbc.OracleDriver!jdbc:oracle:thin:{userid}/@pabaix08:1521:crcp");
            oIconnectionInfo.setUserName("crcuser");
            oIconnectionInfo.setPassword("crcuser1");
        propertyBag.put("Connection String",ConnStr);
        propertyBag.put("Server Type", "JDBC (JNDI)");
        propertyBag.put("Database Class Name", driver);
        propertyBag.put("Database DLL", "crdb_jdbc.dll");
        PropertyBag bag = new PropertyBag();
        bag.put(PropertyBagHelper.CONNINFO_CRQE_LOGONPROPERTIES, propertyBag);
        bag.put(PropertyBagHelper.CONNINFO_CRQE_DATABASETYPE, "JDBC (JNDI)");
        bag.put(PropertyBagHelper.CONNINFO_DATABASE_DLL ,"crdb_jdbc.dll");
        oIconnectionInfo.setAttributes(bag);
        oConnectionInfos.add(oIconnectionInfo);
     catch(Exception e) {
     return oConnectionInfos;
