Check if range checks can be moved into Java wrapper for intrinsics

    XMLWordPrintable

    Details

      Description

      Some of the String related intrinsics have range checks in the intrinsic itself instead of having a Java wrapper (see John's comment here [1]). We should investigate if we can safely move the checks into the Java code while avoiding problems like JDK-8142303. We can probably make use of the intrinsified Preconditions.checkIndex().
