guard against integer overflow in write()

[jmestwa-coder]

Summary

Add a guard in ByteArrayOutputStream.write(...) to prevent integer overflow when calculating the new size.

Problem

The size is tracked using an int . When total data exceeds Integer.MAX_VALUE, count + len overflows and becomes negative.Since Wicket uses multiple buffers, this can happen without hitting JVM array limits.

Impact

• size() may return a negative value

• toByteArray() can throw NegativeArraySizeException

• Leads to inconsistent behavior and possible data loss

Fix

Add a simple overflow check and fail fast with IndexOutOfBoundsException.

Notes

• No change for valid inputs

• No API changes

• Minimal, safe fix
