IO error. Error:

Error message

IO error. Error:

What it means

Guard in ProfilerConfigLoader.loadProperties: reading the agent configuration InputStream via PropertyUtils.loadProperty threw IOException; the message prefixes the underlying I/O error text. Fires when the profiler config stream (e.g. pinpoint.config) cannot be read.

Solutions

1. Check the appended Error: text for the real IOException cause (missing file, closed stream, permission)
2. Verify pinpoint.config path and readability in the agent directory
3. Ensure the InputStream passed in is open and non-null
