Bug#742864: ITP: openjdk-8 -- OpenJDK 8 - Open source implementation of the Java Platform Standard Edition 8
After further investigation the error I encountered was caused by GNU Make 4.0. Erik Joelsson from Oracle kindly provided a patch [1] and I've been able to build the compact JREs. I did a quick test with headless applications to see the difference in startup time between the full JRE and the compact1 profile. I measured the time to run 'mvn -version' and 'ant -version' 100 times. The compact JRE was faster by 6-7% only. With clirr the compact JRE was ~13% faster. With an average startup time of ~100ms the difference was hardly noticeable. Now I wonder if packaging the compact JREs is really worth the trouble.

Emmanuel, Disclaimer: I haven't done any work on Debian Java, so my opinion isn't here isn't worth anything. :-) If I understand correctly, the difference between the profiles is simply the number of Java packages available at runtime [0]. Whether the compact1 profile is worth packaging despite only a 6-7% improvement in startup times depends on whether performance improvement is the only benefit we think is worthwhile with these profiles. Here's my take: 1. If you only need features from the compact1 profile, then you only need to install this profile 2. If there is an exploitable vulnerability in some other code (e.g. JavaEE), but you do not have any software installed that needs it, then the existence of this compact1 profile means that your system is not vulnerable to the problem. If on the other hand, you are forced to install the full profile, then you could be vulnerable (e.g. forcing some class to be loaded via Reflection and exploiting it). But: * I suppose this is just theoretical; and * I'm by no means a security expert; and * There are also costs to packaging/maintaining the profile So ultimately, a decision will have to be made with these considerations in mind.

Le 30/05/2014 07:32, Daniel Svensson a écrit : It would be nice if there are multiple versions of the jre-package, one normal, and one for each of the compact profiles: https://blogs.oracle.com/jtc/entry/a_first_look_at_compact Hi Daniel, That's an interesting idea. I tried to build the compact JRE images with 'make images profiles' but I got this error: ## Starting profiles make[2]: Entering directory '/home/ebourg/openjdk8/jdk/make' make[3]: Entering directory '/home/ebourg/openjdk8/jdk/make' make[3]: *** No rule to make target '/home/ebourg/openjdk8/build/images/beanless/java/util/jar/Pack200\$Packer.class', needed by '/home/ebourg/openjdk8/build/images/libprofile_1/rt.jar'.

We'll have to introduce new virtual packages, I suggest java8-runtime-compactn. As I understand the compact profiles do not contain UI classes, so there is no need to have -headless variants here. - What would be the install directory for the compact JREs? Currently the full JRE/JDK is installed in /usr/lib/jvm/java-8-openjdk-arch. The compact JREs could go into /usr/lib/jvm/java-8-openjdk-compactn-arch.

Hi, Created repo on https://admin.vdu.lt/gitweb/?p=openjdk-8.git and pushed my changes (git clone https://admin.vdu.lt/git/openjdk-8.git). To build new version sources http://87.98.165.193/checkjdk.php needs to be updated. For now package builds successfully, but openjdk-8-jre-headless is huge and JDK/JRE is slow then in use.

Hi Miguel, The package isn't building yet, without IcedTea debian/rules needs some modifications to work properly. I'll let you know when you can start playing with the package, help will be welcome to refresh some of the patches.
