> Running into a situation where calling an EJB2 BMP finder method that returns more than
256 entities causes subsequent finder calls in the same sessionbean transaction to fail.
>  
> {code:java}
> BigFinderHome bigFinderHome = (BigFinderHome)lookup("BigFinderHome");
> LittleFinderHome littleFinderHome = (LittleFinderHome)lookup("LittleFinderHome");
> for (int i = 1; i < 300; ++i) {
>   // this is a test finder that returns "i" number of entities
>   // once this returns more than 256 it causes the littleFinderHome.findAll
>   // to return BigFinder entities instead of the LittleFinder entities!
>   bigFinderHome.findN(i);
>   Collection littleList = littleFinderHome.findAll();
>   for (Object obj: littleList) {
>     if (!(obj instanceof LittleFinder)) {
>       StringBuilder msg = new StringBuilder();
>       msg.append("Failed with " + i + " records. LittleFinder Remote is actually " +
obj.getClass().getName() + " Implemented interfaces " + Arrays.toString(obj.getClass().getInterfaces()));
>       if (obj instanceof EJBObject) {
>         Object pk = ((EJBObject)obj).getPrimaryKey();
>         msg.append(" Primary key value is " + pk);
>       }
>       throw new EJBException(msg.toString());
>     }
>   }
> }{code}
>  
> I can replicate this 100% of the time by deploying the attached ztest.ear application
and running the FinderTestBean.main function (same as the above code). I have tried this on
TomEE versions 1.7.3 and 7.0.5 and they both have the error.
> The error output of my test is as follows
> 09-07 12:25:13 [SEVERE] EjbTransactionUtil.handleSystemException: Failed with 257 records.
LittleFinder Remote is actually com.sun.proxy.$Proxy142 Implemented interfaces [interface
ztest.BigFinder, interface java.io.Serializable, interface org.apache.openejb.core.ivm.IntraVmProxy] Primary
key value is 1
>  
> Note that in my test I am configured to use simple jndi lookup names in the system.properties
> openejb.jndiname.format=\\{interfaceClass.simpleName}
