(fs) FileChannel.write(ByteBuffer[] srcs) throws IOException with -d64 Flag

    • solaris_7

      java.nio.FileChannel.write(ByteBuffer[] srcs) throws IOException with -d64 Flag , I tried on Solaris 7(64 bit) and solaris 8(64 bit) and this fails on both.

      -----------TestCase-----------------

      public boolean writeGatheringTest01() {
      String testName = "writeGatheringTest01" ;
      String fileName = testName + partialFileName ;
      int bufferCapacity = 3 ;
      int numBuffers = 3 ;
      int totalCapacity = bufferCapacity * numBuffers ;
      ByteBuffer[] srcBuffers = new ByteBuffer[numBuffers] ;
      FileChannel fc = Helper.openWriteFileChannel(new File(fileName));
      int bytesWritten = -10 ; // some invalid value
      if (fc == null) {
      TestHelper.testFail(testName + " FAIL ") ;
      }

      for (int i = 0 ; i < numBuffers ; i ++) {
      // initial position = 0, and limit = capacity
      srcBuffers[i] = ByteBuffer.allocate(bufferCapacity) ;
      // set limit = position = 0 (buffer empty)
      srcBuffers[i].flip();
      }

      try {

      // no data available in any of the buffers.
      // write() should write 0 bytes and return 0
      if ((bytesWritten = fc.write(srcBuffers)) != 0) {
      return TestHelper.testFail(testName +
      " FAIL: bytesWritten expected = 0" +
      ", actual = " + bytesWritten + ", pos = " + fc.position()) ;
      }
      } catch (Exception e) {
      return TestHelper.testFail(testName + " FAIL: unexpected exception ! ", e);

      }

      return TestHelper.testPass(testName + " PASS");

          }
