Environment:
PlantUML Version: 1.2023.13
IDE: IntelliJ IDEA 2023.2.5
Operating System: Kubuntu 23.10
Java Version: openjdk 17.0.9 2023-10-17 (OpenJDK Runtime Environment build 17.0.9+9-Ubuntu-123.10; OpenJDK 64-Bit Server VM build 17.0.9+9-Ubuntu-123.10, mixed mode, sharing)
Description: Encountered a fatal parsing error in PlantUML when accessing the second element of a split string array. The function $getAttributeName is designed to split a string like "Address_id;1-1" at the semicolon, resulting in an array ["Address_id", "1-1"]. Accessing the first element with $splitAttributes[0] returns "Address_id" as expected. However, attempting to access the second element with $splitAttributes[1] results in a "Fatal parsing error" in PlantUML.
Steps to Reproduce:
Use the $getAttributeName function to split a string at the semicolon.
Access the first element of the resulting array, which works as expected.
Attempt to access the second element of the array.
Expected Result: Accessing the second element should return "1-1" without errors.
Actual Result: PlantUML throws a "Fatal parsing error". Additionally, when running through the console, an "index out of bounds" error is observed, despite the log showing the correct attribute.
Additional Information:
A simplified version of the code excluding the full context works as expected, suggesting a potential issue with state management or memory references in PlantUML.
Renaming the $split variable to avoid potential conflicts (e.g., splitAttributes) does not resolve the issue.
The issue might be related to PlantUML's internal handling of arrays or string operations.
Attachments:
Terminal output showcasing the error.
Complete code where the error occurs.
Simplified version of the code where the error does not occur.
Notes: Open to suggestions or insights that might indicate a different cause for this issue. The behavior suggests a potential bug in PlantUML's handling of array element access or string manipulation.
I do not get how to upload the file, hence I paste it here, sorry :/ :
