The problem was that on zulu8 loading OkHttp touches JFR which in turn
touches log manager - which would break things like JBOSS.
The fix is to delay installing agent (and writer) until log manager
things have settled down - in way similar to jmxfetch.
Unfortunately for 'main' agent this turns out to be more involved
because of classloader shenanigans.
Postfix the existing config names with `-beta` for `servlet` and `jdbc`.
To avoid any risk that the config was explicitly enabled for an unrelated reason resulting in unexpected behavior when upgrading to the latest version.
Turns out the class level path annotation overrides parent classes, so we only need to find the nearest one.
We also need to look from the instance’s class, not from where the method is defined.
Commented out a test case because we still need to compile against java 7. That case will be added back when we upgrade to java 8.
- reproduce NPE error with JaxRs class and interfaces in JavaInterfaces
- fix the logic target class of method with @Path annotation to avoid NPE
- setting java 1.8 for jaxrs's test
Sometimes servlets will call another servlet by “resetting” the request object. This maintains the attributes previously set, including the span. We want to allow the trace to start if there’s no “active trace” even if there is a span attribute.
Disabled by default, and only creates a span if existing trace detected.
To enable:
* System Property: `-Ddd.integration.jdbc.enabled=true`
* Environment Variable: `DD_INTEGRATION_JDBC_ENABLED=true`
(Or more specifically with `jdbc-datasource`.)
Disabled by default, and only creates a span if existing trace detected.
To enable all of them:
* System Property: `-Ddd.integration.servlet.enabled=true`
* Environment Variable: `DD_INTEGRATION_SERVLET_ENABLED=true`
(They have independent configs as well. If needed, view the source below.)
For spring:
* Move more logic to the decorator.
* Use a fixed operation name, but set the resource name.
* Rename the root span instead of the parent span (If there are other spans in between this could make a difference.) Not sure what impact this would have if multiple controllers are called (ie, forward/include).
For Jax-rs:
* Rename the root span instead of the parent span (same concern as above with spring)
