When using EnvInject's option
"Inject passwords to the build as environment variables" with password parameter masking
and timestamper the timestamps in the console log are shifted by two lines (and the last two lines don'T have timestamps).
These two lines are probably
[EnvInject] - Inject global passwords.
[EnvInject] - Mask passwords passed as build parameters.

But why do they cause a shift?

The second problem ist, when viewing the log while the job is still running newly added lines do not get timestamps. I have to reload the page to see timestamps.

Both problems are gone for jobs without EnvInject passwords.
