Daniel Sun updated GROOVY-9237:
-------------------------------
Fix Version/s: 3.0.0-rc-1
> GContracts and Groovy3
> ----------------------
>
> Key: GROOVY-9237
> URL: https://issues.apache.org/jira/browse/GROOVY-9237
> Project: Groovy
> Issue Type: Bug
> Reporter: Paul King
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 3.0.0-rc-1
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> The following runs fine in 2.5.8 (needs gcontracts and asm jars on classpath):
> {code}
> import org.gcontracts.annotations.Invariant
> import groovy.transform.*
> @Invariant({ month >= 1 && month <= 12 && day >= 1 && day <= lastDay[month-1]
> })
> @MapConstructor
> @ToString(includeNames=true)
> class Calendar {
> private static final int[] lastDay = [31,29,31,30,31,30,31,31,30,31,30,31]
> int month
> int day
>
> def mutateByOneMonth() {
> month++
> }
> }
> new Calendar(month: 2, day: 2).mutateByOneMonth() // Okay
> new Calendar(month: 12, day: 2).mutateByOneMonth() // ClassInvariantViolation
> new Calendar(month: 1, day: 31).mutateByOneMonth() // ClassInvariantViolation
> {code}
> but with 3.0.0-beta-3 I get:
> {noformat}
> java.lang.IllegalAccessError: tried to access method
> org.codehaus.groovy.ast.stmt.EmptyStatement.<init>()V from class
> org.gcontracts.generation.TryCatchBlockGenerator
> {noformat}
> We should check whether we have made an unneeded breaking change or whether a
> gcontracts upgrade might be needed.
