Problem
Your builds fail due to Tasks for AWS encountering an java.lang.OutOfMemoryError: Java heap space:

Solution
This problem is caused by an upstream bug introduced in Bamboo 5.9.1 and addressed in Bamboo 5.12.0.2:
BAM-17488 - Getting issue details... STATUS
Accordingly, you can address it by either upgrading Bamboo to a release that contains a respective fix, or by updating to Tasks for AWS 2.10.4, which provides a respective workaround (refer to https://utoolity.atlassian.net/browse/UAA-168 for details).
Feature flag
The workaround avoids the build log flooding by skipping the creation of variables if they are password variables (variable name contains "password", "awsSecretKey" or "passphrase") and the variable value contains only asterisks.
For the (unlikely) case that this would affect any existing build configurations, the workaround can be disabled by setting a global or plan variable utoolity.flags.disableWorkaroundForBAM17488 to true.
