OpenJDK Cacao GCJ Java defaults in unstable
Hi,
openjdk-6 in unstable is updated to the 6b14 code drop, built from a recent
IcedTea snapshot. There are a few regressions in the ports which don't use the
hotspot VM, but the Zero VM. Help from porters would be appreciated.
There are two new binary packages offering additional JVMs:
- openjdk-6-jre-zero: built on amd64 and i386. This is the JVM used by
default on the non-hotspot archs (armel, alpha, s390, mips, mipsel,
powerpc, m68k?). Maybe useful for debugging issues with the zero JVM on
archs which are more accessible.
- icedtea-6-jre-cacao: built on alpha, armel, mips, mipsel, s390, i386,
amd64, powerpc). The Cacao JVM and JIT is not yet feature complete
compared to the hotspot JVM, but is much faster than the Zero JVM
and offers an alternative on platforms which don't have the Hotspot
JVM.
The additional JVM's can be called with
java [-cacao|-zero]
or for the java tools with
tool name [-J-cacao|-J-zero]
This is currently a Debian/Ubuntu only option; integration into IcedTea is in
progress.
To make a JVM the default, make it the first one in /etc/java-6-openjdk/jvm.cfg.
GCJ is still the work horse to build and bootstrap OpenJDK. IMO it still does
make sense to keep the '-gcj' packages for software which is known to work with
GCJ. I plan to have a recent GCJ-4.x release for the next Debian release.
Once openjdk-6 moves to testing, I propose to change the default in the
default-{jre,jdk} packages to point to the openjdk-6 packages. This works well,
except for one thing: packages will be built with -source 1.6 by default, which
makes the resulting .class/.jar files unusable with older java versions (1.4 and
1.5). I would like to propose a change in the Debian java policy, that java
packages must be built for the version which is sufficient for a sucessful
build. The changes are trivial; I already did check in changes for ant and ant
build- and runtime dependencies into the debian-java svn.
There is currently work-in-progress to extend the Zero JVM with a JIT (called
shark). This is still experimental work, currently requires llvm-2.4 (unstable
has 2.5). I would welcome feedback from port maintainers about zero/shark.
Please consider to join the IcedTea mailing list.
Matthias
PS: I would appreciate some help with openjdk in Debian; the current maintainer
team is MIA or inactive.

Re: bsh-gcj package breaks Iceweasel javascript functionality.
Hi Ananda, After debugging with iceweasel-dbg, I found the the following message given a few times during the times that the process hung: *** NSPlugin Wrapper *** ERROR: NPP_New() invoke: Message timeout and, the same problem was occurring with iceape and epiphany web browser. I see that nspluginwrapper debian pkg in Lenny was upgraded to 0.9.91.5-1 from 0.9.91.4-4. According to the nspluginwrapper web site, this new version was released Aug 26, 2007) includes new support for 64-bit plugins, and support for broken 64-bit Konqueror. Perhaps the problem is in one of these 64 bit related upgrades, because after downgrading to 0.9.91.4-4, my plugins are working again no problem. I will attempt to notify the package maintainers for nspluginwrapper or file a bug for it or something.

Re: bsh-gcj package breaks Iceweasel javascript functionality.
Unfortunately, the problem has resurfaced with iceweasel. I purged anything with gcj in the name, including all of openoffice.org, and still no luck. I will try to build iceweasel from the source package and see if I can't debug it. -Steve levis501 wrote: Hi Ananda, I believe you should log this as a iceweasel bug, and here's why.

build eclipse-gcj
Hi, I have installed eclipse (3.2.1) via repository. Always in repos I have found eclipse-gcj version. Is there a tutorial, guide, how-to etc. to build eclipse in native way using that packages on Debian? I have not found anything about it...

Re: java sun and gcj problem
Probably eclipse installs uses gcj and not java-sun.
It is using gcj as a VM at least, see the libgcj in your error above.
How can I
come back to old situation (using java sun)?
with 'update-alternatives' I got:
# update-alternatives --config javac
There is only 1 program which provides javac
(/usr/lib/j2sdk1.5-sun/bin/javac). Nothing to configure.
And what does
# update-alternatives --config java
say?
Caused by: java.lang.ClassNotFoundException: java.lang.StringBuilder
not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./],
You got your compiler right (Sun) probably, but the runtime is surely
the gcj one.
Hi Edwin,
# update-alternatives --config java
There are 3 alternatives which provide `java'.
SelectionAlternative
---
1/usr/lib/j2sdk1.5-sun/bin/java
2/usr/bin/gij-wrapper-4.0
*+3/usr/lib/jvm/java-gcj/bin/java
Press enter to keep the default[*], or type selection number: 1
Using `/usr/lib/j2sdk1.5-sun/bin/java' to provide `java'.
I have selected first argument and now it works:)
Thank you very much,
Giulio
