> The {{SmbStreamDownloadIT.testStreamDownload}} test fails consistently on main with:
> {code}
> expected: <World\n> but was: <>
> {code}
> When {{streamDownload=true}}, the consumer wraps the SMB file handle in a {{SmbFileClosingInputStream}} and sets it as the exchange body. However, by the time the test reads the {{InputStream}} from the exchange, the stream returns empty content.
> This is a stream lifecycle / timing issue: the underlying SMB file handle is being closed or the stream consumed before the test (or a downstream processor) can read it.
> Note: this is *not* the same class of bug as CAMEL-24088 (FTP streamDownload). The FTP issue was about unchecked null returns and ignored completion status. The SMB code correctly throws {{SMBRuntimeException}} on open failures. The SMB problem is that the stream content is lost between the consumer setting the body and the downstream processor reading it.
