Assert preconditions in ResourceDatabasePopulator [SPR-11690]

[spring-projects-issues]

Sam Brannen opened SPR-11690 and commented

Status Quo

ResourceDatabasePopulator currently does not assert any preconditions for constructor and method arguments. Consequently, errors will not be encountered until the populator is executed.

---

Deliverables

1. Ensure that preconditions for constructor and method arguments are asserted immediately.

Completed as described in the comments for GitHub commit 84f678a:

Assert preconditions in ResourceDatabasePopulator

Prior to this commit ResourceDatabasePopulator did not assert any
preconditions for constructor and method arguments. Consequently,
errors would not be encountered until the populator was executed.

This commit addresses this issue by ensuring that preconditions for
constructor and method arguments are asserted immediately, throwing
IllegalArgumentExceptions where appropriate.
