JVM can't load shared libraries on Caldera Open Linux 2.3
I assume that JDK was built under Redhat6.1 which has
newer shared libraries than Caldera Open Linux 2.3

---------------------------- output with comments --------------------------
[kotl@linux-7 kotl]$ java -hotspot -version
/.automount/novo48/root/export/home1/jdk1.3/linux/bin/i386/native_threads/java: error in loading shared libraries:
/.automount/novo48/root/export/home1/jdk1.3/linux/jre/lib/i386/native_threads/libhpi.so: symbol sem_init, version GLIBC_2.1 not defined in file libpthread.so.0 with link time reference

I've copied /lib/libpthread-0.8.so from RedHat to Caldera with the name /lib/libpthread-0.8.new.so
And than linked new library.

[kotl@linux-7 kotl]$ su
Password:
[root@linux-7 kotl]# cd /lib
[root@linux-7 /lib]# rm libpthread.so.0
[root@linux-7 /lib]# ln -s libpthread-0.8.new.so libpthread-0.8.so

[kotl@linux-7 /lib]$ ls -la libpthread*
-rwxr-xr-x 1 root root 247381 May 15 13:51 libpthread-0.8.new.so
-rwxr-xr-x 1 root root 79583 Aug 11 1999 libpthread-0.8.so
lrwxrwxrwx 1 root root 21 May 18 15:21 libpthread.so.0 -> libpthread-0.8.new.so
[kotl@linux-7 /lib]$

 Libc on Caldera 2.3 has also older version than on Redhat 6.1.

[kotl@linux-7 kotl]$ java -hotspot -version
/.automount/novo48/root/export/home1/jdk1.3/linux/bin/i386/native_threads/java: /lib/libc.so.6: version `GLIBC_2.1.2' not found (required by /lib/libpthread.so.0)
[kotl@linux-7 kotl]$

I've copied new libc library from Redhat to Caldera and linked it

[kotl@linux-7 /lib]$ ls -la libc*
-rwxr-xr-x 1 root root 1245005 Aug 11 1999 libc-2.1.1.so
-rwxr-xr-x 1 root root 4118299 May 15 13:44 libc-2.1.2.so
lrwxrwxrwx 1 root root 13 May 18 14:36 libc.so.6 -> libc-2.1.2.so
lrwxrwxrwx 1 root root 17 May 15 18:16 libcom_err.so.2 -> libcom_err.so.2.0
-rwxr-xr-x 1 root root 7606 Aug 11 1999 libcom_err.so.2.0
-rwxr-xr-x 1 root root 25471 Aug 11 1999 libcrypt-2.1.1.so
lrwxrwxrwx 1 root root 17 May 15 18:11 libcrypt.so.1 -> libcrypt-2.1.1.so

 After that everything works fine:

[kotl@linux-7 kotl]$ java -hotspot -version
java version "1.3.0beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta-b05)
Java HotSpot(TM) Client VM (build 1.3.0beta-b03, mixed mode)
[kotl@linux-7 kotl]$

----------------------------------------------------------
If you try this and find that java can't find /bin/grep,
make symbolic link to grep:
[kotl@linux-7 kotl]$ su
Password:
[root@linux-7 kotl]# cd /bin
[root@linux-7 /bin]# ln -s /usr/bin/grep grep

Suggestion fix:
To build JDK with older libc and libpthread shared libraries.
