----------------------------------
Summary: NPE occurred when `null` message passed into
`MissingPropertyException`
Key: GROOVY-8936
URL: https://issues.apache.org/jira/browse/GROOVY-8936
Project: Groovy
Issue Type: Bug
Reporter: Daniel Sun
Assignee: Daniel Sun
Fix For: 3.0.0-alpha-4
Reported by Jesse Glick( https://github.com/jglick )
[https://github.com/apache/groovy/pull/844]
Otherwise you get errors like
{{groovy.lang.MissingPropertyExceptionTest > testNullMessage FAILED
java.lang.NullPointerException at
groovy.lang.MissingPropertyException.getMessageWithoutLocationText(MissingPropertyException.java:66)
at
groovy.lang.GroovyRuntimeException.getMessage(GroovyRuntimeException.java:63)
at java.lang.Throwable.getLocalizedMessage(Throwable.java:391) at
java.lang.Throwable.toString(Throwable.java:480) at
junit.framework.Assert.assertNull(Assert.java:268) at
junit.framework.TestCase.assertNull(TestCase.java:438) at
groovy.lang.MissingPropertyExceptionTest.testNullMessage(MissingPropertyExceptionTest.java:29)
}}
it is unclear what null values for {{property}} and {{type}} would mean, but
there is a constructor explicitly allowing that, and it is illegal for
{{getMessage}}, {{toString}}, etc. to throw an undeclared NPE.
(A {{MissingPropertyException}} producing this error was originally observed as
a build failure in a Jenkins project, though I do not have the details to know
the root cause there.)
