A DESCRIPTION OF THE PROBLEM :
As the following test case shows, When I try to” Arrays.fill(newArray, oldCapacity, newArray.length, UNSET);",happens error and return -9.Howerer,HotSpot-jdk17, HotSpot-jdk11,OpenJ9-jdk17,Openj9-jdk11, Zulu-jdk17, Zulu-jdk11, GraalVM-jdk11, GraalVM-jdk17 all return 0 and output correctly.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
536870912
536870912

harness return 0
ACTUAL -
536870912

harness return -9
