Default Problems running jdk-1.7

I just installed jdk-1.7, but it doesn't quite work. I have /usr/local/jdk-1.7.0/bin in my PATH. When I run java or javac, I get this:

Code:
$ javac
Error: could not find libjava.so
Error: Could not find Java SE Runtime Environment.
If I give the full path to the binary, it runs fine. libjava.so is located in /usr/local/jdk-1.7.0/jre/lib/i386/libjava.so. I tried adding it to the arguments sent to ldconfig, but all that happens is this:

Code:
$ sudo ldconfig /usr/X11R6/lib /usr/local/lib /usr/local/jdk-1.7.0/jre/lib/i386
$ ldconfig -r | grep jdk
        search directories: /usr/lib:/usr/X11R6/lib:/usr/local/lib:/usr/local/jdk-1.7.0/jre/lib/i386
Anybody have better luck than me?

Also I'm running -current, and I really wish I gave this thread a better title. ... TITLE FIXED!

I don't run 1.7, but creating symlinks in 1.6 has worked for me:
Code:
# ln -sf /usr/local/jdk-1.6.0/bin/java /usr/local/bin/java
# ln -sf /usr/local/jdk-1.6.0/bin/javac /usr/local/bin/javac

No dice. 1.5 and 1.6 behave nicely: when I have it in my PATH, it works fine. Also, this works regardless of PATH:

Code:
$ cd /usr/local/jdk-1.7.0/bin
$ ./java
[reams of output]
$ cd .. ; bin/java
[same]
$ cd .. ; jdk-1.7.0/bin/java
[same]
So, it seems like Java is finding the libraries by using getcwd() and argv[0]. This is clearly a horrible idea since it makes working with PATH impossible. I don't know how java 1.5 and 1.6 found the libraries, but it was definitely a different method.

The only solution besides changing the source code is messing with the linker. Currently, ldconfig does not see any of the libraries in /usr/local/jdk-1.7.0/jre/lib/i386 and I can't figure out why.

I also tried setting JAVA_HOME and JDK_HOME to /usr/local/jdk-1.7.0.

My suggestion would be to contact the port maintainer & ask him. The appropriate email address can be found by issuing the following command:

$ cd /usr/ports ; make search key=jdk

Once you have resolution, it would be great if you would report here what was both the issue & solution.

Default resolved, kind of

So it was an issue with dladdr(), bug compatible with Solaris by the looks of it. Changing one line of the source code fixes it. The maintainer probably won't commit the change because of a ports soft-lock for 4.4, so in the meantime, you can either apply it yourself or make some shell scripts to do the work for you:

The change will make it in despite the lock, so it appears we will all get a working JDK/JRE in the next OpenBSD release without having to accept Sun's license agreements and spend half a day compiling.

No, the above discussion is specific to the JDK 1.7 port only for current users who are not running what is presntly in the -current ports tree. I built -current as of yesterday & can say firsthand that the above fix was been checked in for JDK 1.7.
