-----------------------------------
Summary: StackOverflowError in DefaultPropertyVisibilityStrategy
Key: JOHNZON-276
URL: https://issues.apache.org/jira/browse/JOHNZON-276
Project: Johnzon
Issue Type: Bug
Components: JSON-B
Affects Versions: 1.2.1
Reporter: Markus Karg
The following code produces a StackOverflowError:
@JsonVisibility(DefaultPropertyVisibilityStrategy.class)
public final class C {
@JsonProperty private boolean foo;
}
The problem is caused by the fact that this strategy tries to compare "this" by
"==" with a _new instance_ of itself, which certainly fails, because the new
copy is definitively a different reference than the one currently executed and
instantiated due to the class annotation.
The fix is simple: Adding an equals method just comparing the class type (as
the strategy has no members other than a cache), and calling that instead of
"==".
