There is a thread about it here that may help :https://www.b4x.com/android/forum/t...rror-b4j-8-90-jdk1-8-0_171.129085/post-810204

I'm still struggling with compilation errors. It's getting uncomfortable, I wonder how I'm going to get started again. I think it's some type of virus, although no security program reacts and warns of something like that. ctrl P dont help!
I use ExifTool for read metadata!

suddenly impossible

This implies it does work in the past.

Provide the jar file with the package com.drew.imaging

Yes, but there have been many problems with other compilation stops, often with a red screen, but not so long-lasting.
After a couple of compilations, it has worked.

But now I don't know what to do?

java uses unchecked or unsafe operations

How old is the easy media jar?
Which version of Java did it work on?

If you were using java 8, the jar may not be compatible with later java. Check if there is an updated jar file.

 

[johnerikson]

I use java 14.0.1 and b4j 10.20 as well as windows11.
Have always upgraded to the latest versions, worked well.
I wonder if this is a virus.
I have another computer that runs on Windows 10. On that I run the server solution.
It first showed this compilation error, but it released after a few minutes, but not on the development machine.

I don't understand what you mean by easy media jar, how old it is?

I meant the version. I presume it's the metaextractor https://github.com/drewnoakes/metadata-extractor which is currently version v2.19.0.

The problem is solved!
It was because < sign had come in a Dim declaration, 'Dim < as string' The compiler did not detect the error and java complained about that declaration. Java does not have the explanation where in the code the error occurs. By comparing the code files and backup files with the WinMerge tool, I was able to locate where the error was.

Sounds like a bug to me. You should make a short thread about it and simply link to this thread from it.
