A DESCRIPTION OF THE PROBLEM :
In an array constructor reference like String[]::new the array type may be annotated. However, if both array type and its element type are annotated, e.g.
@Anno1 String @Anno2 []::new
the compiler crashes with exception.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the provided executable test case with javac.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The compilation succeeds.
ACTUAL -
javac crashes with the following stack trace:
