[aspectj-dev] Analysis of aspectj-1.8.2's dependency on JDK-Internal APIs
|
Hi Andy,
As part of the preparations for JDK 9, Oracle’s engineers have been
analyzing open source projects like yours
to understand usage. One area of concern involves identifying
compatibility problems, such as reliance on
JDK-internal APIs.
Our engineers have already prepared guidance on migrating some of
the more common usage patterns of
JDK-internal APIs to supported public interfaces. The list is on the
OpenJDK wiki [0], along with instructions
on how to run the jdeps analysis tool yourself .
We have analyzed jar files within aspectj-1.8.2
and found 0 jar files depending on JDK-Internal-APIs.
However, jdeps is a static analysis tool and therefore use of
JDK-internal APIs via reflection or dynamically
generated bytecode are not reported by the tool, while such a
dependency should also be replaced.
If you have any feedback please reply either on this list or to me
directly.
Rgds,Rory

Title: JDK Internal API Usage Report for aspectj-1.8.2
JDK Internal API Usage Report for aspectj-1.8.2
The OpenJDK Quality Outreach campaign has run a compatibility report to
identify usage of JDK-internal APIs. Usage of these JDK-internal APIs
could pose compatibility issues, as
the Java team explained in 1996. We have created this report to help you identify
which JDK-internal APIs your project uses, what to use instead, and where
those changes should go. Making these changes will improve your compatibility,
and in some cases give better performance.
Migrating away from the JDK-internal APIs now will give your team adequate time
for testing before the release of JDK 9. If you are unable to migrate away
from an internal API, please provide us with an explanation below to help us
understand it better. As a reminder, supported APIs are determined by the
OpenJDK's Java Community Process and not by Oracle.
This report was generated by jdeps
through static analysis of artifacts: it does not identify any usage of those
APIs through reflection or dynamic bytecode. You may also
run jdeps on your own if you would prefer.
Summary of the analysis of the jar files within aspectj-1.8.2:
- Numer of jar files depending on JDK-internal APIs: 0
- Internal APIs that have known replacements: 0
- Internal APIs that your team should migrate away: 0
