Java CAD Loading dwg file exception：Exception: Cannot process loading further due to incorrect file format structure

Aspose.CAD Product Family

The dwg file（version is AC1027） can be viewed in CAD software, and when I tried to load the dwg file, the program reported an error.

Program runtime environment：
JDK11，aspose-cad:24.3

This line of code throws an exception：
CadImage image = (CadImage) Image.load(dwgFilePath);

error prompt：
Caused by: class com.aspose.cad.internal.Exceptions.Exception: Cannot process loading further due to incorrect file format structure, may be file is corrupted. Invalid optcode ‘7’ value.

I need your help, thank you!

@fsolsh,
I can confirm the issue unfortunately. We have created CADJAVA-11659 task to investigate and resolve this. It could be helpful if you can share what software writes this DWG file.
