B4J Question How my greatmother can kill B4J on a PI ?

[CR95]

After several investigations, I summmarize the issue as follows :
In a B4J UI program, I create a B4XImageView and I load it with "Load(File.DirAssets, "1984 06 GreatMother.JPG").
Under Windows, It works well.
Under Raspberry, the "LoadFile...." line kills the job with :

I guess this is coming either from a bad installation of Java (I am using Liberica Full Java 17 version under Dietpi), either form a corrupted JPEG file.
Any idea ?

If it is a corrupted file (But my Greatmother image is correctly showed with other packages like Picture Manager or Paint....), is there a way to detect it ?

I cannot join MyGreatMother picture (too large) !

I have a vague memory that dirasset files are made to have lower case names when compiling. For Windows this wouldn't matter, but Linux considers lower case different from upper case. So take a look inside your compiled jar and see what the case is, and make sure you adjust the code to request the correct name.

Liberica Full Java 17 version - under Linux and under Windows also Liberica?

As far as I can remember, there are issues loading JPEG format in Linux. Something related to license or library if I am not mistaken.

Better use PNG format.

issues loading JPEG format in Linux

In all Linux ? Or some JDK versions ?

I am having issue in Manjaro last time. Can't remember much.

There is a use to prepare for you an small app example to test by forum team under Linux variants...
