[iText-questions] Patch for java.lang.NoSuchMethodError at PdfDate

[Finn Bock]

Hi,

Recently there have been a couple of bug reports when running under 
jdk1.3 and lower when iText was compiled with jdk1.4. The exception 
looks like this:

java.lang.NoSuchMethodError
 at com.lowagie.text.pdf.PdfDate.<init>(Unknown Source)
I would hope that the problem could be solved at the source level by 
avoiding calls to the method:

    StringBuffer.append(StringBuffer)

It would make life a little easier for those of us who compile iText our 
selfs.

It is a minor problem, but it is a bit annoying that I can't compile 
with jdk1.4 and run on jdk1.3.

regards,
finn
