Hi Devs,
The error [1] is reproducible with 4.1.4 Stratos release. This can be
reproduced by undeploying the application + cartridge, and then re-adding
them, followed by deploying them from UI. This is occurring due to a race
condition, when we are validating the partitions in parallel using
PartitionValidatorCallable class. The getIaaS method of IaaSProvider [2],
used in validatePartitionAndGetIaasProvider method of
ClousControllerServiceUtils class [3] is not thread safe. We can use the
buildIaaS method of same class, which is thread safe. I have tested this
fix and it works as expected. Created issue [4] to track.
