[jira] [Created] (GROOVY-7449) power operator needs specific typing
for result
Christopher Smith created GROOVY-7449:
-----------------------------------------
Summary: power operator needs specific typing for result
Key: GROOVY-7449
URL: https://issues.apache.org/jira/browse/GROOVY-7449
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 2.4.3
Reporter: Christopher Smith
Priority: Minor
I wanted to use the power operator to set a static constant field:
{code}
public static final int DIGITS_IN_CODE = 4
static final int mod = 10 ** DIGITS_IN_CODE
{code}
This results in a compile-time exception when used with {{@CompileStatic}}:
{code}
Groovy:[Static type checking] - Cannot assign value of type java.lang.Number to variable of type int
{code}
Replacing the symbolic constant with just {{10 ** 4}} produces the same bug. It appears that power expressions are not getting resolved until runtime even if they're compile-time constant expressions.
