New page

[[JDK]]8 is about to provide three new [[profiles]]. In addition to classical, full, bloated [[Java]] runtime, there will be:
* Compact 1 (small, about 4600 classes)
* Compact 2 (also adds [[XML]] and [[JDBC]] [[API]]s)
* Compact 3 (the rest except UI and [[CORBA]])
As [[Harmony]] story illustrates, [[profiles]] are the best thing since sliced bread. Moreover they are ready (at least if you are running [[Linux]]) right now. I've just tried:

<source lang="bash">
$ hg clone http://hg.openjdk.java.net/jdk8/jdk8 openjdk8
$ cd openjdk8
$ bash ./configure
$ make clean profiles
</source>

and after few (tens of) minutes I could switch to the profile image and test it on [[Felix]]:

<source lang="bash">
$ cd build/linux-x86-normal-server-release/images/j2re-compact1-image/
$ ./bin/java -version
openjdk version "1.8.0-internal"
OpenJDK Runtime Environment (build 1.8.0-internal_2013_11_27_13_39-b00, profile compact1)
OpenJDK Server VM (build 25.0-b60, mixed mode)
$ ../bin/java -jar bin/felix.jar
