Taack opened a new issue, #16010:
URL: https://github.com/apache/grails-core/issues/16010
### Expected Behavior
Our app should launch without exception, even if database DDL are executed.
### Actual Behaviour
An exception is thrown:
```
WARN 78010 --- [ main] o.h.t.s.i.ExceptionHandlerLoggedImpl :
GenerationTarget encountered exception accepting command : Error executing DDL "
alter table if exists application_message
alter column body set data type varchar(32600)" via JDBC [ERROR:
value too long for type character varying(32600)]
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing
DDL "
alter table if exists application_message
alter column body set data type varchar(32600)" via JDBC [ERROR:
value too long for type character varying(32600)]
```
### Steps To Reproduce
1. Create a domain class with a mapping:
```groovy
@GrailsCompileStatic
class ApplicationMessage {
String body
static constraints = {
}
static mapping = {
body type: 'text'
}
}
```
2. Use `bootRun` task, it should fail at startup with a similar message than
above.
