emerge dev-java/ant fails with sun-jdk-1.4.2_04

iainmcgin

There appears to be a bug in the javac compiler that is part of sun-jdk-1.4.2_04, which means that when you run "emerge ant" it falls over. I've submitted it to the sun bug parade but they said it could take up to 3 weeks for it to even appear on the bug parade

I tried sun-jdk-1.5.0-beta1 as well, but that gives a different error related to accessing /dev/random (there are other posts that have mentioned this, see https://forums.gentoo.org/viewtopic.php?t=136953
and https://forums.gentoo.org/viewtopic.php?t=140058).

Has anyone else tried to emerge ant recently and found a way to get it to work? Is there an ebuild that can be used just to install ant in binary form instead of compiling the java sources? I don't really see why it needs to be compiled from source, as the JAR files are portable anyway.

Here's the error, to help people find this post if they've got similar problems:

According to the Gentoo Java Guide http://www.gentoo.org/doc/en/java.xml, not everything will work with jdk 1.4.

One suggestion is to emerge jdk 1.3 and use that for ant.

You can have multiple jvms and switch between them as required.

Well, ant-1.6.1 compiled just fine for me with sun-jdk-1.4.2_04, got to be something different.

Do you know what it could be that is affecting the java compiler? Perhaps glibc or something similar? This is really starting to frustrate me because it's affecting other Java packages also. I'll probably leave my system doing an emerge --update system overnight to see if that helps.

Voltago · Posted: Sat Mar 27, 2004 1:41 am Post subject:

Could be glibc, since it is the only platform library dependency of java (that i'm aware of). I'm using glibc-2.3.2-r9 with nptl flag turned on, encountered no problems so far. Which version are you using? And does Sun tell against which version they compiled the jdk?

Well even after running emerge --update system and acquiring the latest version of glibc, I am still unable to compile ant. The version of glibc I have a the moment is:

I have been having all sorts of problems with sun-jdk-1.4.2_04 - can't emerge ant, can't run the ant I have installed...this is really becoming a pain. Is your error message like this (when I try to run ant):

iainmcgin · Posted: Sat Mar 27, 2004 11:22 pm Post subject:

Yeah, if you look at the Hotspot virtual machine error and error ID that I gave in the first post, it's the same as yours. So, we both have the same irritating problem. As I mentioned earlier I filed the bug report with Sun but it could take up to three weeks for them to even acknowledge it

If downgrading to 1.4.2_03 works for you, let me know. I was considering doing this also, but I can't find the download on java.sun.com (sun handily remove all old version from the main pages).

Is anyone else experiencing similar problems? If so, post here so we can figure out what makes us different to Voltago who has it working.

When did you download and install 1.4.2_04? I noticed for several days that there were reports that the 1.4.2_04 bin file had been removed from the Sun website. I assume there was something wrong with the package or they would not have removed it.

I just upgraded to 1.4.2_04-r1 today, and reinstalled the latest ant, and there were no issues. I am however running glibc 2.3.2-r9.

I downloaded the JDK again from Sun, and it didn't make any difference; I still get the same JVM error. I'm downgrading my glibc to 2.3.2-r9 just now, once that's compiled I'll see if it works. If it does, should I file a bug report on gentoo to have the 2.3.3 builds masked until this is resolved?

iainmcgin · Posted: Sun Mar 28, 2004 1:51 am Post subject:

glibc 2.3.2-r9 doesn't work either, I still get the same VM crash. What else could it be?

Voltago · Posted: Sun Mar 28, 2004 2:02 am Post subject:

Is anyone of you (if you are getting this error) using nptl?

iainmcgin · Posted: Sun Mar 28, 2004 2:26 am Post subject:

No, as far as I can tell I'm not using NPTL anywhere, from what I can see of that thread you linked you have to explicitly enable it. Here's the output that /lib/lib.so.6 gives me:

It appears this problem is related to gentoo-sources-2.4.25 kernel. See bug report 45595 for the details - it's currently been assigned to the x86-kernel team. Voltago, or anyone who has it working, what kernel version do you have? If it is 2.4.25, maybe we should attach our kernel .config files and do a diff to see if it is a particular kernel option?

iainmcgin · Posted: Sun Mar 28, 2004 2:56 pm Post subject:

I've just upgraded my kernel to 2.6.5-rc2, and I was just able to emerge ant without any problems. So the problem is definitely to do with the gentoo-sources-2.4.25 kernel. Still, this was a good excuse to upgrade to a 2.6 kernel

I have just re-emerged ant 1.5.4 with no problems...

ant 1.6.1-r1 emerged successfully too.

I am running 2.4.24-xfs sources. I backed down to the 1.4.1-01 of Blackdown (because it was on my machine) and didn't have any problems with emerging ant 1.6.1

Guess I will need to upgrade to 2.6 and see if it corrects the problem for me as well.

I downloaded Sun-jdk prior to the removal incident. I redownloaded and it did not fix the problem for me either.

I haven't tried going to the 1_03 sun-jdk yet...I do have the download though.

I've uploaded my config to my university webspace, you can view it here (i thought it unwise to post my entire config here considering how long it is

)

This should hopefully serve as an example of a config that breaks Java.

Well, due to a suggestion posted on the bug report I tried recompiling my 2.4.25 kernel without grsec. It appears that my java works just fine without grsec on the gentoo-sources 2.4.25 kernel. This is certainly a feasible workaround on my laptop (on which I am the only user) although not so much for my server, heh

Hope this helps someone else!

To update my troubles:
backing down to the Blackdown 1.4.1 was not as successful as I thought. It seems javac still has problems but more sporatically. I can run ant and java will crash and then run it again and it will work.

I am currently in the midst of getting my file server back up and running and then will upgrade my workstation to 2.6.x

Do people recommend vanilla or gentoo-dev for 2.6.x sources?

Just wanted to update this thread. I upgraded my system to 2.6.3 (gentoo-dev-sources) and "javac" is working, consistently.

This is from the Gentoo grsecurity maintainer:

You need to chpax/paxctl your java bins.
This kinda falls under a know issue with java*

If your using EI_PAX flags then try chpax -zsp /path/to/java/bin/*
If you compiled with PT_PAX support then try paxctl -sp /path/to/java/bins/*

99% chance this bug can be closed as INVALID
