Here are three files, all of which compile with javac:
import java.lang.annotation.ElementType;
import java.lang.annotation.Target;
@Target({ElementType.TYPE_USE, ElementType.TYPE_PARAMETER})
@interface MyTypeAnno {}
public class GjfFailure {
void m(int a @MyTypeAnno []) {}
}
import java.lang.annotation.ElementType;
import java.lang.annotation.Target;
@Target({ElementType.TYPE_USE, ElementType.TYPE_PARAMETER})
@interface MyTypeAnno {}
public class GjfSuccess {
void m(int @MyTypeAnno [] a) {}
}
import java.lang.annotation.ElementType;
import java.lang.annotation.Target;
@Target({ElementType.TYPE_USE, ElementType.TYPE_PARAMETER})
@interface MyTypeAnno {}
public class GjfSuccess2 {
void m(int a[]) {}
}
Running google-java-format (version 1.7) on the first file yields this stack trace:

The code is in bad style as it uses a deprecated placement of array brackets in a variable declaration. However, it's legal code and google-java-format probably shouldn't crash.
