Okay, those are benign. The IntelliJ IDEA plugin SDK logs that when you request a reindex. Let's go ahead and get detailed info about the retrieval. Go into Help>Debug Log Settings and add the following two entries:
#com.illuminatedcloud.intellij.builder.ForceComBuilder
#com.illuminatedcloud.intellij.builder.ForceComMetadataRetriever
Then run a retrieval again and it'll show me exactly what's going on. If there's sensitive information in the log, feel free to email it to me at "support at illuminatedcloud dot com". I'll let you know what I find.
Regards,
Scott
