[jira] [Updated] (GROOVY-8454) Method with wrong argument typed is
called when passing 'null'
[ https://issues.apache.org/jira/browse/GROOVY-8454?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul King updated GROOVY-8454:
------------------------------
Description:
The output of the following code is 'Map: null' instead of 'String: null'
{code:java}
class Stat {
def static m(String s) {
println 'String: ' + s
}
def static m(Map m) {
println 'Map: ' + m
}
}
class Main {
def run() {
String n = null
Stat.m(n)
}
def static void main(String ... args) {
new Main().run()
}
}
{code}
To get the correct output I must explicitly cast the null value to String.
{code:java}
Stat.m((String)n)
{code}
was:
