resourceconfig.json not including resources correctly

[lyap1010]

User defined resourceconfig.json doesn't include the resources correctly.

This issue is due to ConfigResolver looking for the following exact starting string for each line:
{"pattern"

Expected Behavior

resourceconfig.json should enable the defined resource pattern to be included as per JSON defined structure.

Current Behavior

The following resource pattern definition will fail to include the resources.
Expectation - this format should work:

[
  {
    "resources": [
      {
        "pattern": ".*\\.xml$"
      },
      {
        "pattern": ".*\\.properties$"
      }
    ]
  }
]

Following definition works - resources are loaded

[
  {
    "resources": [
        {"pattern": ".*\\.xml$"},
        {"pattern": ".*\\.properties$"}
    ]
  }
]

Hi @lyap1010,

You're right—currently, GluonFX expects the resourceconfig.json to strictly follow the predefined format, typically the one generated by the --native-image-agent during runtime profiling.

This means that even minor formatting differences (like spacing or line structure) can cause the resources to be ignored, as the ConfigResolver performs exact matches starting with {"pattern" on each line.

Hopefully, future versions will support a more flexible or fully spec-compliant JSON parser. But for now, it's best to stick with the agent-generated format or ensure your custom file exactly mirrors that structure.

Thanks for pointing this out!
