Problem with include

[loms0815]

Used Eclipse Version: 2024-12 (4.34.0)
Used PlantUML Version: 1.2024.5

Test case:
"test.puml" includes file "test.iuml" (which includes only one "version" command).
If "test.puml" is selected in Project-Explorer then version will be shown in PlantUML view (as expected).
After Eclipse restart "test.puml" is still selected but there rises an error in PlantUML view "cannot include test.iuml".
