Current Behavior

Hi team!

I have created sample Java files to test analysis against. When running assessments, we noticed rules with patterns ending in or () are not triggering. This results in missing issues in the generated static report.

For the attempt I have run for this issue the command I ran was: ./kantra analyze --input ./sample1/ --target azure-appservice --output ./sample1-output --overwrite

I believe on the sample code, which is attached, this app-service rule should have triggered and added an incident in the static report. However, I only observe a single rule being triggered with respect to Windows style pathing in the code.

Please let me know if I performed any steps/categorized incorrectly! This is my first issue in this repo 😄

Expected Behavior

The rule linked above would trigger and additional incidents would appear in the static report.

How Reproducible

Always (Default)

Steps To Reproduce

1. Download the sample Java code attached to this issue.
2. When running an assessment, set the target to azure-appservice.
3. Execute the assessment.
4. Observe that the rule "09-eap-to-azure-appservice-environment-variables.windup.yaml" with the following patterns did not return results:
   • java.referenced: location: METHOD_CALL pattern: java.lang.System.getenv(*)
   • java.referenced: location: METHOD_CALL pattern: java.lang.System.getProperty(*)

Anything else?

The result of the latest analysis on the attached sample I performed using the above Kantra version. Yields only one issue:

This view is to show the sample code with the Java function calls. I believe we should see more issues when these are present in the code.

I have been taking a quick look at this and it seems that there is a problem when matching method calls in general. We will need to take a deeper look into it.
