Brett Walker commented on AXIS2-5190:
-------------------------------------
I have since found the root cause of this issue. It is related to a bad URI.
But the structure of the following method hid the root cause:
/**
* @param returnArray
* @param baseArrayClass
* @param objectList
*/
private static void ConvertToArbitraryObjectArray(Object returnArray,
Class baseArrayClass,
List objectList) {
if (!(ADBBean.class.isAssignableFrom(baseArrayClass))) {
try {
for (int i = 0; i < objectList.size(); i++) {
Object o = objectList.get(i);
if (o == null) {
// if the string is null the object value must be null
Array.set(returnArray, i, null);
} else {
Array.set(returnArray, i, getObjectForClass(
baseArrayClass,
o.toString()));
}
}
return;
} catch (Exception e) {
//oops! - this cannot be converted fall through and
//try the other alternative
}
}
try {
objectList.toArray((Object[])returnArray);
} catch (Exception e) {
//we are over with alternatives - throw the
//converison exception
throw new ObjectConversionException(e);
}
}
A MalformedURIException was being throw in the top half of the method resulting
in the bottom half being executed. This threw the ArrayStoreException. By
ignoring the exception I was unaware of the root cause. No attempt was made to
log the error. If a warning message appeared in the log that would have been
very helpful. I have wasted almost a day in debugging this problem.
