Hi Bill
I got an exception when I ran this test (client-side) (this thread
is running ten times at the same time):
-------------------------------------------------------------------
class RegularTeller
implements Runnable
{
public void run() {
int k = 0;
Random lRandom = new Random();
Category lLog = Category.getInstance( getClass().getName() );
try {
// Get bank first
Collection lBanks = getBankSession().getBanks();
System.out.println( "RegularTeller.run(), banks: " + lBanks );
BankData lBank = (BankData) lBanks.iterator().next();
while( !mExit && mException == null ) {
CustomerData lCustomer = null;
if( lRandom.nextInt( 100 ) < 10 ) {
lCustomer = getCustomerSession().createCustomer(
lBank.getId(), "test", 100 );
System.out.println( "RegularTeller.run(), new " +
lCustomer );
} else {
List lCustomers = (List) getBankSession().getCustomers(
lBank.getId() );
System.out.println( "RegularTeller.run(), # of customers:
" + lCustomers.size() );
lCustomer = (CustomerData) lCustomers.get(
lRandom.nextInt( lCustomers.size() ) );
}
}
-------------------------------------------------------------------
the exception on the server-side:
-------------------------------------------------------------------
javax.transaction.TransactionRolledbackException: removing bean lock and it
has tx set!; nested exception is:

This happens on my computer (W2K, 256MB, Pentium IV) after 1000 customers
are created. As you can see the test creates a new customer on every 10th
loop
otherwise it will retrieve all customers from the JBoss server.
Is this a known problem or shall I add it to the bug list ?
