Paul King updated GROOVY-9131:
------------------------------
Description:
The following two method reference statements compile and execute successfully
with and without @CS (and with CS produce the correct native bytecode):
{code}
assert 'Hi'.transform(String::length) == 2 // transform is JDK12
assert 'Hi'.transform(StringGroovyMethods::size) == 2
{code}
This statement (using the extension method from StringGroovyMethods) works for
dynamic Groovy:
{code}
assert 'Hi'.transform(String::size) == 2
{code}
But for static Groovy fails compilation with:
{noformat}
1 compilation error:
org.codehaus.groovy.syntax.RuntimeParserException: Failed to find the expected
method[size(java.lang.String)] in the type[java.lang.String]
{noformat}
