Created attachment 235645 [details]
Test code to reproduce the issue

ArrayTypeReference generated for argument is incorrect.

Expected: int [] @TakeType(int[].class) [] 
Actual: int @TakeType(int[][].class) []

(only 1 dimension shown in actual, while the 2nd dimension is shown as part of annotations).

public class X {
  int bar(int [] @TakeType(int[].class)[] a) { return 0; }
}

@Target(ElementType.TYPE_USE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@interface TakeType {
	Class value() default int[].class;
}

Note: there is a parameter "a" in bar. The modified test case inlined above.

Good catch, thanks. It helps always to provide a full test case that does
not show any errors outside of what it is supposed to show. Here it is:

Good catch. I'll take this one:

Test case:

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

public class X {
  int bar(int [] @TakeType(int[].class)[] x) { return 0; }      
}

@Target(ElementType.TYPE_USE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@interface TakeType {
	Class value() default int[].class;
}
