RE: Strange exception while dealing with strings

["Gary L Peskin" <garyp@xxxxxxxxxxxx>]

This bug was previously reported to Sun.  You haven't mentioned what
version of the JDK you're on so it's difficult to pinpoint without that
information.  It probably involves a high surrogate character (\uD800
through \uDBFF) that is not followed by a low surrogate character as
required by Unicode.

What you might want to do is catch the Error (this is not an Exception
but is an Error) in Inv2PDF.  Then, go character by character and try to
convert each character to a byte.  Something like this:

  try
  {
    byte[] ba = myString.getBytes();
  }
  catch (UnknownError ue)
  {
    ue.printStackTrace();
    for (int i = 0; i < myString.length; i++)
    {
      char thisChar = myString.charAt(i);
      System.err.println("Now converting character " + i + " (" +
thisChar + ") "
            + Integer.toHexString((int) thisChar));
      byte thisByte = ("" + thisChar).getBytes();
      System.err.println("Conversion of character " + i + "
successful");
    }
  }

This should show you what character of the String is causing the
problem.

You might try migrating to a more recent JDK or opening a PMR to ask for
a better message.
