Fix size overflow in AbstractDiskHttpData (#15463)

qchole · web-flow · commit 757296c4efaf · 2025-07-11T11:26:54.000-07:00
Motivation:
The local variable `written` is int in
`AbstractDiskHttpData#setContent(InputStream)`, if the inputstream size
is larger than max value of int, it will overflow, as a result the
`size` will be wrong

Modification:
make `written` long

Result:
`size` does not overflow
