During times when Dependency-Track server is experiencing maxed-out CPU usage, the dependency-track-plugin (operating in synchronous mode) will endlessly poll the DT server. The Jenkins job will continue running until it is aborted, logging the following to the console:

[DependencyTrack] Publishing artifact to Dependency-Track
[DependencyTrack] The artifact was successfully published
[DependencyTrack] Polling Dependency-Track for BoM processing status
[DependencyTrack] Polling Dependency-Track for BoM processing status
...

The polling should have a timeout limit and then fail.

This was originally reported as part of reporting high CPU usage in DT server (issue #264 and has been re-logged here in order to aid change control.

Commits have already been made to address the defect. eg:

Added polling timeout
