Apache NetBeans (Incubating)
[ANNOUNCE] Apache NetBeans (incubating) 9.0 Beta released
The Apache NetBeans team is proud to announce the release of Apache NetBeans (incubating) 9.0 Beta.
Apache NetBeans 9.0 Beta (incubating) constitutes all the modules in the Apache NetBeans Git repo, which together provide the NetBeans Platform (i.e., the underlying application framework), which was released as Apache NetBeans 9.0 Alpha (incubating), as well as all the modules that provide the Java SE-related features of Apache NetBeans. In short, Apache NetBeans 9.0 Beta (incubating) is a full IDE for Java SE development.
Note: Apache NetBeans (incubating) 9.0 Beta is primarily focused on IP clearance. Its functionality has not been tested — the NetCAT (NetBeans Community Acceptance Testing) process will begin now that Apache NetBeans (incubating) 9.0 Beta has been released. Watch this space for upcoming announcements about NetCAT. When NetCAT completes, we will vote on the final release of Apache NetBeans (incubating) 9.0.

The case of the different jsch 0.1.54 binaries
As part of the Apache NetBeans IP clearance we are combing through all the code and dependencies.
One interesting thing we bumped into was that the jsch 0.1.54 binary JAR we are using has a different hash (and size) than the binary JAR from Maven Central.
The old hash is 0D7D8ABA0D11E8CD2F775F47CD3A6CFBF2837DA4, the new one is DA3584329A263616E277E15462B387ADDD1B208D.
The binaries are 278,612 bytes vs 280,515 bytes in Maven Central.
Our version is actually the same as the one found on http://www.jcraft.com/jsch/
Also, the Maven JAR is properly signed with the author's CA7FA1F0 key.
This is where it becomes clear that reproducible builds are important. You do not want to have to wonder why a binary differs, especially years later when you are doing a review. And this one is a library doing SSH!
So, why the different binaries?
It seems the original JAR was compiled on Aug 30, 2016 with Java 1.4 (major version 48) while the Maven Central JAR was compiled Sep 3, 2016 with Java 5 (major version 49).
The original JAR also concatenates strings using
StringBuffer while the Maven Central JAR uses the newly introduced in 1.5
StringBuilder. Which should also be a bit faster since it's not synchronized.
Next, most of the cypher classes use some reflection via a
static java.lang.Class class$(java.lang.String) method.
What is this? It's just the way class literals worked in Java 1.4. As explained here, in Java 5 the
ldc_w instruction was introduced to load a
In 1.4 the class literal was helped by the compiler by actually introducing the helper
Class class$(java.lang.String className) method and replacing the
Person.class with a
It conclusion, it seems that excluding the Java 1.4 to Java 5 compiler changes, the two JARs are identical. With the Maven Central JAR even a bit better due to
StringBuilder being used.
There is no check so far that the sources do produce the specific JAR. This is an exercise left for the reader.

Introducing the Apache NetBeans Blog
Here, at last, is a community space for everyone working on Apache NetBeans, currently incubating, to post blogs.
I imagine this will be a place where we can announce new releases of Apache NetBeans, while it will also be a place for everyone to share their experiences and make all kinds of other announcements.
For example, did you know there's already an application created on top of Apache NetBeans? It is called YaMeter, read about it here.
Happy blogging everyone, at the brand new Apache NetBeans (incubating) blog.
