Q:

After upgrade from SonarQube 4.5.4 LTS to 5.3, Ant analysis unable to delete files

We recently upgraded from Sonarqube 4.5.4 LTS to 5.3.  After the upgrade, we've been encountering a problem with an analysis conducted via the SonarQube Scanner for Ant.
The relevant log error message:
...
Caused by: java.io.IOException: Unable to delete file: C:\build-dir\PUM-PUM30SONAR-JOB1\.sonar\cache\ff4174ae66dafc76b7dd3adbf9942334\sonar-pmd-plugin-2.5.jar_unzip\META-INF\lib\sslr-xpath-1.20.jar

The analysis conducted immediately prior to the SonarQube upgrade was fine.  Every execution after that has failed with this error.
So, it's like the build successfully creates this cache directory, but then when it tries to clean it up, it fails.  No issues reported by any builds using Maven or sonar-runner.

Continuous Integration Application:  Bamboo 5.7.2 
Build Agents: Windows 2008 Server, happening on multiple agents 
Builds affected:only one confirmed, but maybe more
SonarQube 5.3 
Ant 1.9.3 
SonarQube Scanner for Ant 2.4

What I have tried:

verified that the Bamboo agent service is running as the correct user, and files can be deleted manually
cleaned the build dir from the agent manually
forced the build to run on an alternate agent
