Compile the code below using the Nullness checker throws an exception asking to
report a bug, but it should instead compile without warnings:
import org.checkerframework.checker.nullness.qual.*;
public class Test {
public void foo() {
try {
return;
} catch (@NonNull Exception e) {
}
}
}
This test passes by removing the @NonNull annotation or by removing the return
call in the try block.
The exception can be seen below:
An exception has occurred in the compiler (1.8.0-jsr308-1.8.4). Please report
this bug so we can fix it. For instructions, see
http://types.cs.washington.edu/checker-framework/current/README-jsr308.html#repo
rting-bugs . Thank you.

Thanks for the bug report!
This is a langtools bug and not caused by the Checker Framework.
Minimal test case that crashes jdk9 javac:
import java.lang.annotation.*;
class TestIssue344 {
public void foo() {
try {
return;
} catch (@TA Exception e) {
}
}
}
@Target(ElementType.TYPE_USE)
@interface TA {}
Note that this test works with jdk8 javac and if TA is a declaration annotation.
There were some big type annotation refactorings in jdk9 and something broke.
Thanks for finding this!
I'll file a bug report.
