Tilman Hausherr commented on PDFBOX-3815:
-----------------------------------------
That strategy might not be the best one: you are losing document level
information, especially metadata.
I tried reproducing the effect with a large number of files with this code, but
nothing happened:
{code}
try (PDDocument doc = PDDocument.load(f))
{
if (doc.getNumberOfPages() > 1)
{
int oldPageCount = doc.getNumberOfPages();
doc.getPages().remove(0);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
if (doc.isEncrypted())
{
doc.setAllSecurityToBeRemoved(true);
}
doc.save(baos);
try (PDDocument doc2 = PDDocument.load(baos.toByteArray()))
{
int newPageCount = doc2.getNumberOfPages();
if (oldPageCount - 1 != newPageCount)
{
System.err.println("unterschiedlich: " + f);
}
}
}
}
{code}
I could do some research if you can post a screenshot of the page structure
with PDFDebugger command line app. Click "View, Show internal structure", and
then go to Root/Pages and expand that structure.

> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.6
> Environment: Windows 10, Java 8; PDF 1.5
> Reporter: Sascha Becher
>
> Does nothing to page 1:
> try (PDDocument doc = PDDocument.load(file)) {
> doc.removePage(0);
> doc.save(file);
> doc.close();
> }
> This would remove page 2:
> doc.removePage(1);
> seems not to be new:
> https://stackoverflow.com/questions/37865415/pdfbox-does-not-remove-first-page
> If there are any restrictions to removing pages, the javadoc should note this.
