I guess you could avoid such problems using mapping. Here's some example code, modified from an example:
// Original code from 'Thinking in Java, 3rd ed.' (c) Bruce Eckel 2002
// www.BruceEckel.com. See copyright notice in CopyRight.txt.
import java.io.RandomAccessFile;
import java.nio.MappedByteBuffer;
import java.nio.channels.FileChannel;
static int length = 0x8FFFFFF; // 128 Mb
public static void mapThis (String file) throws Exception {
    MappedByteBuffer out = new RandomAccessFile(file, "rw")
        .getChannel().map(FileChannel.MapMode.READ_WRITE, 0, length);
    byte b;
    if(!out.isLoaded()) out.load();
     for (int i = 0; i < length; i++) {
         b = out.get(i);
         manipulate(b);
As for Bertram's solution, couldn't get it to work properly in a dynamic use case - I'm getting the input stream from IResource, and I get a ClassCastException everytime I use something different from InputStream. With that problem comes another one: InputStream.read() consuming the first byte from the file, which is a problem when dealing with PDF and DOC files, for example. Since I know the users are opening PDF files, made a quick-and-dirty workaround by inserting manually the missing byte. Really dirty one, actually - the byte changes with the file format. Below is the code I used - it works, but I'd love to see a different workaround.
public void openFile( )
    //@@begin openFile()
        //KM files are shown in a table
        //get index of selected table row
     int i = wdContext.nodeTableContent().getLeadSelection();
     //get the name of the according object (resource)
     String name = wdContext.nodeTableContent().getTableContentElementAt(i).getObjectName();
     String path = wdContext.currentContextElement().getPath();
     try {
     RID pathRID = RID.getRID(path"/"name);
     IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
     com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
     IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
     IResourceContext resourceContext = new ResourceContext(ep5User);
     com.sapportals.wcm.repository.IResource resource = ResourceFactory.getInstance().getResource(pathRID, resourceContext);
     InputStream in = null;
     in = resource.getContent().getInputStream();
     int bSize = 10 * 1024;
     byte[] bArr = new byte[bSize];
     ByteArrayOutputStream baos = new ByteArrayOutputStream ();
     int offset = 0;
     int data;
     //dirty!
     String ext = name.substring(name.length()-3);
          if("pdf".equalsIgnoreCase(WDWebResourceType.getWebResourceTypeForFileExtension(ext).getFileExtension())) {
          byte b = '%';
          baos.write(b);     
     while ( (data=in.read(bArr)) != -1)
     baos.write(bArr);
     IWDAttributeInfo pdfAttributeInfo = wdContext.getNodeInfo().getAttribute(IPrivateKMBrowserAppCompView.IContextElement.PDF_RESOURCE);
     IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) pdfAttributeInfo.getModifiableSimpleType();
     binaryType.setFileName(name);
        binaryType.setMimeType(WDWebResourceType.getWebResourceTypeForFileExtension(ext));
     wdContext.currentContextElement().setPDFResource(baos.toByteArray());
     } catch (Exception e) {
