I can't get embed a color space in a pdf for Pdf/A creation

Question

Here is my problem, I've made a java program with the library PdfBox to make pdf from the image and other pdf so this work fine, but I want to generate PDF/A-1 . The problem is that I can't embed a color space.

I've tried the code of CreatePDFA.java that is given by PDFBox

// Create output intent
InputStream colorProfile = CreatePDFA.class.getResourceAsStream("colorSpacePath");
PDOutputIntent oi = new PDOutputIntent(doc, colorProfile); 
oi.setInfo("sRGB IEC61966-2.1"); 
oi.setOutputCondition("sRGB IEC61966-2.1"); 
oi.setOutputConditionIdentifier("sRGB IEC61966-2.1"); 
oi.setRegistryName("http://www.color.org"); 
doc.getDocumentCatalog().addOutputIntent(oi);

I get a NullPointerException at the line:
PDOutputIntent oi = new PDOutputIntent(doc, colorProfile);

Exception:

Here is the code that work :

InputStream colorProfile = new FileInputStream(colorSpacePath);
PDOutputIntent oi = new PDOutputIntent(doc, colorProfile);
oi.setInfo("sRGB IEC61966-2.1");
oi.setOutputCondition("sRGB IEC61966-2.1");
oi.setOutputConditionIdentifier("sRGB IEC61966-2.1")
oi.setRegistryName("http://www.color.org");
doc.getDocumentCatalog().addOutputIntent(oi);
colorProfile.close()
