Cannot use constants in Priority

[ysmartin]

I am trying to annotate some statements with an @Priority annotation whose value is defined as a constant in a different module:

create constant variable int DEBUG_PRIORITY = Integer.MAX_VALUE;

Then I try to refer that constant from an @Priority annotation

@Name('DebugXXX')
@Audit
@Priority(DEBUG_PRIORITY) // We want debug consumer statements to execut and print their result before other consumers
select *
from XXXType;

But I get this exception when trying to load the module:

2018-02-15 18:04:19,854 ERROR [AnnotationUtil] Unexpected exception compiling annotations in statement, please consult the log file and report the exception: java.lang.String cannot be cast to java.lang.Number

(detailed logs are attached, once internal data has been removed; note that it is the console output, I do not know about the location of the logs file there mentioned.)

I know that a workaround may consist on wiring the value into the priority annotation; but in any case, that ClassCastException makes little sense, as there is no String involved in the whole process (there is a java.lang.Integer constant, then an EPL int variable).
