Unable to easily suppress dependency exception using java agent

[petergphillips]

Expected behavior

I was hoping to suppress an exception using exception.message or exception.stacktrace that is flooding our logs - 900,000 times a day.

Actual behavior

I only appear to be able to suppress the exception using exception.type.

To Reproduce

I started off followed the steps detailed in Span Attributes Available for Sampling to look for the exception. Whilst I can see all the dependencies exported that way, it appears that the exceptions are exported differently and don't appear with text exporting span. In my case I can see the exception as json in the log, for example

{
  "ver": 1,
  "name": "Exception",
  "time": "2023-06-19T11:41:42.152Z",
  "iKey": "b44af8fc-1647-443d-8cea-55c5cfbd4518",
  "tags": {
    "ai.internal.sdkVersion": "java:3.4.13",
  },
  "data": {
    "baseType": "ExceptionData",
    "baseData": {
      "ver": 2,
      "exceptions": [
        {
          "typeName": "java.sql.SQLException",
          "message": "ORA-06550: line 1, column 28:",
          "stack": "java.sql.SQLException: ORA-06550: line 1, column 28:\nPLS-00302: component 'GETMAXIDENTIFIERLENGTH' must be declared..."
        }
      ]
    }
  }

I can get the suppression working with configuration such as

          "telemetryType": "exception",
          "attributes": [
            {
              "key": "exception.type",
              "value": "java.sql.SQLException",
              "matchType": "strict"
            }
          ],
          "percentage": 0

but would ideally like to match on the message or stacktrace instead. According to the opentelemetry exception documentation I think I should be matching on exception.message or exception.stacktrace, but can't get either to work. For example I think:

          "telemetryType": "exception",
          "attributes": [
            {
              "key": "exception.stacktrace",
              "value": ".*GETDBCOMPATMAJORVERSION.*",
              "matchType": "regexp"
            }
          ],
          "percentage": 0

should do the trick, but the exception still appears in the logs. I've also tried suppressing the dependency, which works fine with the above regexp but doesn't suppress the corresponding exception.

Please could you let me know the key that I need therefore to match on the stacktrace and / or message to suppress the exception. Looking at the Oracle code that throws the exception it appears to be caught and doesn't then affect the behaviour of the application, hence the reason for the suppression.
