yurloc opened a new issue, #5920:
URL: https://github.com/apache/incubator-kie-drools/issues/5920
## Parent issue
- #5678
## Failing tests
- `org.drools.mvel.integrationtests.StrictAnnotationTest#*`
## Notes
The strict parser (`LanguageLevelOption.DRL6_STRICT`) allows strongly typed
and prefix annotations. Should the new parser support that as well?
## Rule code snippet
```
rule R1 when
@Watch( "!value" ) $m : MyClass( value < 10 )
then
modify( $m ) { setValue( $m.getValue()+1 ) };
end
```
## Error output
```
