      Description

        It looks like the removal of the HPI in 6348631 has broken the large file support on Solaris in jdk7-b123. With hs20-b04 it is no longer possible to use java.io.FileInputStream, FileOutputStream or RandomAccessFile to open files >2GB. Other operations that cause the file to grow to larger than 2GB are also impacted.

        I've only briefly looked at the issue but it seems to be that os::open is using ::open rather than ::open64.

        Here are some of the regression tests that are failing:
