- *
- * Test preparation:
- *
- * - Enable file based H2 in ebean.properties (line `datasource.h2.databaseUrl=jdbc:h2:file:~/tests`)
- * - disable logging of io.ebean.SUM/TXN/SQL in logback-test.xml
- * - remove existing database in ~/tests (do that before each run)
- * - run this class with `-Xmx1g` jvm argument
- * - an OOM in iteration ~45000 will occur (45k * 10k chars = 45k * 20k bytes = 900MB)
- *
- * remove the line `@Cache(enableQueryCache=true)` - and it will run forever (until disk is full)
