Description

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:
