permission leads in runtim exception

#38246

Hi.

on setting password in my test run on ubuntu i get every time i try to set a permission this below shown exception.

doing this:
pd4ml.setPermissions(if(password.trim.isEmpty) "empty" else password ,0xffffffff)
I want to modify it with change permissions like this:
pd4ml.setPermissions( "test", Constants.DefaultPermissions ^ Constants.AllowFillingForms )

always getting the same error.

java.lang.NullPointerException: Cannot read the array length because "buf" is null at java.base/java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.java:108) at com.pd4ml.pdf.encryption.s.o00000(y:3227) at com.pd4ml.pdf.parser.obj.f.o00000(y:1998) at com.pd4ml.pdf.parser.d.o00000(y:1818) at com.pd4ml.pdf.parser.d.o00000(y:1849) at com.pd4ml.html.doc.render.to.m.Ò00000(y:1055) at com.pd4ml.html.doc.render.to.f.o00000(y:3119) at com.pd4ml.PD4ML.writePDF(y:1482) at com.pd4ml.PD4ML.writePDF(y:151) at de.heilpraktikerelbmarsch.pdf.PDFPrinter.writePdf(PDFPrinter.scala:80) at core.client.services.PdfServiceController.$anonfun$generatePdf$10(PdfServiceController.scala:358)
