Guillaume Nodet commented on CAMEL-24618:
-----------------------------------------
This issue is being investigated by a coding agent (on behalf of gnodet).
Preliminary analysis confirms the flakiness root cause:
1. The FTP consumer endpoint has no delete/noop/idempotent option, so files
accumulate on the FTP server across test retries.
2. FtpServiceExtension.afterAll() is a no-op ("Restart not supported"), so the
FTP server and its directories are never reset between runs.
3. The initialDelay=2000ms + default resultWaitTime can cause timing races on
slow CI.
These two issues explain both observed failure patterns: Expected <1> but was
<0> (timing race) and Expected <1> but was <9> (accumulated files from retries).
