Benedikt Ritter created GROOVY-9988:
---------------------------------------
Summary: Field is given precedence over getter
Key: GROOVY-9988
URL: https://issues.apache.org/jira/browse/GROOVY-9988
Project: Groovy
Issue Type: Bug
Reporter: Benedikt Ritter
Attachments: test.groovy
If a method references a property and there is a field and a getter for that
field, the field is given precedence over the getter. This is problematic if
the getter does some lazy initialization.
Executing the attached script on Groovy 3.0.7 results in the following error:
{code:java}
❯ groovy test.groovy
Caught: java.lang.NullPointerException: Cannot invoke method length() on null
object
java.lang.NullPointerException: Cannot invoke method length() on null object

{code}
As a work around the code in run() can explicitly call the getter.
