PD4ML hanging forever with "broken" PNG image

#27204

Hi!

Referring to an older subject pdf-generation-troubleshooting-f4/broken-png-image-file-hangs-pd4ml-generator-forever-t650.html

We see this kind of problems still (or again)?

There is code i PD4ML that gets the size of an image, and if width is < 0, it waits 10 ms and then tries again. Forever... In our web app, this happens regularly. Probably this is with a PNG image that Java considers bad in some way. The code (disassembled obfuscated code) looks like this:

public final PixelGrabber new(int var1) {
int var2 = this.Ö00000.getHeight(this.ø00000);
int var3 = this.Ö00000.getWidth(this.ø00000);

while(var2 < 0) {
var2 = this.Ö00000.getHeight(this.ø00000);
var3 = this.Ö00000.getWidth(this.ø00000);
if (this.ÒO0000 != null && this.ÒO0000.length() > 4 && this.ÒO0000.substring(0, 5).toLowerCase().equals("data:")) {
var2 = 1;
var3 = 1;
this.Ö00000 = new BufferedImage(1, 1, 2);
break;
}

try {
Thread.sleep(10L);
} catch (InterruptedException var14) {
;
}
}

The inifinte loop here is the problem. I see two problems here, one beeing the infinite loop, the other being that it ignores the InterruptedException. You should probablty give up here and just add a "broken image" after a number of iterations? Please advise, can we trust PD4ML to handle this some way, or do we need to change to another library?
