Recently Openjdk6 was promoted to main; with today's upload of java-common,
OpenJDK6 is the default java runtime / development kit in main, on all
architectures.
- On amd64, i386, lpia and sparc, the Hotspot VM, including the JIT compiler
is used as the VM.
- On ia64, the Hotspot VM, using the byte code interpreter is used.
- On powerpc, the Cacao VM, including the Cacao JIT compiler is used as the
VM.
What will change for the packaging?
- Use of the default-jre-headless, default-jre, default-jdk,
default-jdk-builddep packages is preferred in favour of a specific
runtime/jdk. The packages provide a symlink /usr/lib/jvm/default-java
to point to our preferred choice of jvm/sdk.
- build dependencies: If a source package builds a "-gcj" package, don't
stop building it yet. This will slow down the gij runtime. Instead,
use "default-jdk-builddep", which depends on the default jdk and
java-gcj-compat-dev. If no "-gcj" package is built, use default-jdk
as a build dependency.
- dependencies: For a dependency, which doesn't require an UI, use
default-jre-headless | java2-runtime-headless
for all other dependencies, use
default-jre | java2-runtime
Replace java2- with java5- only if newer language features are required.
For intrepid we strive to replace all direct references to java-gcj-compat-dev
and java-gcj-compat with references to default-*.
