After debugging more, I found out that I was passing secPermKeyList as
null. Hence I was getting zero results back.
But, after correcting that issue and passing a valid Key list, I get the
following error
Testcase: testSecurityGroup took 1.351 sec
Caused an ERROR

NestedThrowablesStackTrace:
java.lang.IllegalArgumentException: can't operate on multiple entity groups
in a single transaction. found both Element {
type: "SecurityPermission"
id: 2
}
and Element {
type: "SecurityPermission"
id: 1
}
Finally, I have to switch the datasource to 'nontransactional' before
executing the query to make my test pass.
