------------------------------------

             Summary: FinderError returning more than 256 entites from ejb2 finder
                 Key: OPENEJB-2137
                 URL: https://issues.apache.org/jira/browse/OPENEJB-2137
             Project: OpenEJB
          Issue Type: Bug
          Components: general
         Environment: Windows 10 64 bit
            Reporter: Thomas Lien
         Attachments: ztest.ear.zip

Running into a situation where calling a BMP finder method that returns more than 256 entities
causes subsequent finders to fail. The scenario goes like this.

An EJB2 session bean (FinderTest) calls two finder methods for BMPs. The first finder (BigFinder)
returns multiple records. The second finder (LittleFinder) returns just 1 record. If BigFinder
returns more than 256 records, the second finder (LittleFinder) will return BigFinder remote
objects instead of the LittleFinder remote objects that it should! If BigFinder returns 256
entities or less everything works like it should.

I can replicate this 100% of the time by deploying the attached ztest.ear application and
running the FinderTestBean.main function. 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
