iText 7 itextpdf.kernel.PdfException

I'm using java and iText 7 to generate PDF.

I created a PDF template and has some data models inside this template in order to make it dynamic.

When first time I used this template to generate PDF, it worked fine. But second time I tried to modify the data value inside the template then generate again it raised an error.

I isolated the code caused the error, commented out all usage of PdfFont, it worked fine.

I checked a Chinese blog, seems like this error is cause by didn't release some document objects(like PdfFont in my case) when you want to print this PDF again. http://blog.csdn.net/fu250/article/details/52604900

I would much appreciate if someone can give a more detailed answer.

public final PdfFont regular; public final PdfFont bold;

public InvoiceRecieptServiceImpl() throws IOException { this.regular = PdfFontFactory.createFont(FontConstants.HELVETICA); this.bold = PdfFontFactory.createFont(FontConstants.HELVETICA_BOLD); }
