Unable to create LObjectArray greater than Integer.MAX_VALUE

[xxBedy]

Hi,

I'm trying to create huge array of String (or Object):

val arr = LArray.of[String](10L + Integer.MAX_VALUE) or

ClassTag<String> tag = scala.reflect.ClassTag$.MODULE$.apply(String.class) def size = Integer.MAX_VALUE.longValue() + 10 LArray lArray = new LObjectArrayLarge<String>(size, tag)

both failed with exception: java.lang.NegativeArraySizeException was thrown. java.lang.NegativeArraySizeException at java.lang.reflect.Array.newArray(Native Method) at java.lang.reflect.Array.newInstance(Array.java:75) at scala.reflect.ClassTag.newArray(ClassTag.scala:60) at scala.reflect.ClassTag.newArray$(ClassTag.scala:49) at

May be am I doing something wrong ?

Thank you, Bedy

There might be a bug around this code https://github.com/xerial/larray/blob/master/larray/src/main/scala/xerial/larray/LArray.scala#L1106
