NegativeArraySizeException thrown from TextSaver.resize
-------------------------------------------------------
Key: XMLBEANS-474
URL: https://issues.apache.org/jira/browse/XMLBEANS-474
Project: XMLBeans
Issue Type: Bug
Affects Versions: Version 2.5
Reporter: Dan Faershtein
TextSever.resize()
does not check if "newLen" is negative which can happen if requested size is
more than ( Integer.MAX_VALUE / 2)
consider core java implementation AbstractStringBuilder:expandCapacity:
void expandCapacity(int minimumCapacity) {
int newCapacity = (value.length + 1) * 2;
if (newCapacity < 0) {
newCapacity = Integer.MAX_VALUE;
} else if (minimumCapacity > newCapacity) {
newCapacity = minimumCapacity;
}
value = Arrays.copyOf(value, newCapacity);
}
Here is the exception stack trace:
