Mismatched types error E0308 when there is no error

With the new plugin 52, Version: 0.1.0.2069 and using the jni-rs crate, this error is reported at many places in a Rust / JNI codebase.

JObject::from(env.new_string("hello")?);

mismatched types E0308 expected JThrowable, found JString

JString::from(elem_obj)

mismatched types E0308 expected *mut _jobject, found JObject

JObject and JString can be converted to each other using ::from. source: https://github.com/prevoty/jni-rs/blob/master/src/wrapper/objects/jstring.rs#L25

In the meantime, would there be an way to disable this check? It persists after disabling all inspections in IDEA Settings. Thanks!

The issue is still actual for the disabled-by-default inspection =)

@Techcable, the real wizard is @matklad, who patiently created the infrastructure for 2 years, using which I did it in 1-2 lines of code =) You can become a “wizard” like me, just start contributing here!
