Summary: arbitrary Exception: iterator of a CMR..
Initial Comment:
Jboss 3.0.4, CMP2.0 bean, simple business method is called by
remote client. Method declaration is:
public String
getSizeAsString(Locale locale) {
try {
int size = 0;
316:
for (Iterator i = getSlides().iterator(); i.hasNext(); )
{
size+=((Slide)i.next()).getSize();
}
size+=getXml(false,
false, -1, locale).toString().getBytes("UTF-8").length;
return
new
DecimalFormat("0.00").format((double)size/1024D);
}catch
(UnsupportedEncodingException ex) {
throw new
EJBException(ex);
}
}
>From time to time (not every
time, approx one time for 20 invocations) I get the exception below.
All transaction attributes for all beans in application declared
as:
<container-
transaction>
<method>
<description />
<ejb-
name>SMIL</ejb-name>
<method-name>*</method-
name>
</method>
<trans-attribute>Required</trans-
attribute>
</container-transaction>
Looks pretty
much like a bug with instable reproduce. I cannot provide a
testcase as well because it happens rarely. What can be the
cause? Can I help somehow else?
