java.nio.FileChannel scattering read throws IOException with -d64 Flag.I tried with Solaris 7(64 bit). Please see the attached TestCase.


------------TestCase---------
// fc is FileChannel
 try {

if (fc.position() != pos) {
return TestHelper.testFail(testName +
" FAIL : fc.postion() expected = " + pos +
", actual = " + fc.position());
}

// make the buffer ready for read operation
for (int i = 0 ; i < numBuffers ; i ++) {
dstBuffers[i].clear() ;
}

// perform read operation
// verify return value is correct

if ((bytesRead = fc.read(dstBuffers)) != TotalReadCapacity) {
return TestHelper.testFail(testName +
" FAIL (pos=" + pos + "): bytesRead expected = " + TotalReadCapacity +
", actual = " + bytesRead) ;
}

// for each buffer that received scattered data
for (int i = 0 ; i < numBuffers ; i ++) {
// verify that the buffer is completely filled up
// this also verfies claim made is spec: postion is
// guarateed to be equal to limit
if ( ! verifyBufferFullStatus(dstBuffers[i])) {
return TestHelper.testFail(testName +
" FAIL (pos=" + pos + "): dstBuffer[" + i +
"] doesn't appear full ! " + dstBuffers[i]) ;
}


// make the buffer ready for get operation
dstBuffers[i].flip() ;
// get data into the buffer
dstBuffers[i].get(dstData[i]) ;

//use only to demonstrate bug#4452020
//for (int j = 0 ; j < bufferCapacity ; j ++) {
// System.out.println(
// "dstData[" + pos + "," + i +"," + j +
// " ):" + dstData[i][j]) ;
//}


// verify data
for (int j = 0 ; j < bufferCapacity ; j ++) {
int thisByte = expectedDataByte + j + (bufferCapacity * i) ;
if (dstData[i][j] != thisByte) {
return TestHelper.testFail(testName +
" FAIL (" + pos + "," + i +"," + j +
"): byte expected = " + thisByte +
", actual = " + dstData[i][j]) ;
}
}


} // for int i ..

} catch (Exception e) {
return TestHelper.testFail(testName +
" FAIL (pos=" + pos + "): unexpected Exception!", e) ;
}
