The 'jni compatibility symlink'

/usr/java1.2/jre/lib/sparc/libjvm.so -> /usr/java1.2/jre/lib/sparc/client/libjvm.so

(or -> /usr/java1.2/jre/lib/sparc/server/libjvm.so)

being considered for jdk 1.3 on solaris can cause the vm to abort. The
link is needed because the location of libjvm.so is different in jdk1.3
than it was in the solaris production jdk1.2.x.

To reproduce:

Install the packages for jdk1.3 build 18 (or earlier), then

$ cd /usr/java1.2/jre/lib/`uname -p`
$ ln -s client/libjvm.so libjvm.so
$ java -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-b18)
Java HotSpot(TM) Client VM (build 1.3.0-b18, mixed mode)
$ java -server -version
