[APM] Show exception type #69171
Description
Describe the feature:
Exceptions from java agents only show the exception message, not the type. This is especially problematic when the message is null as is frequently the case with exceptions from the core library.
The exception type should be displayed, at minimum in the metadata. Ideally shown on the main listing (e.g. the unqualified name prefixed to the message). The data is available in the error.exception field under type.
Describe a specific use case for the feature:
Trying to find out what a recorded exception actually was.
