In the latest SUNWj3rt the libjavaplugin_oji140.so is missing and is called libjavaplugin_oji140_00.so. Library name should not have version info in it. The ideal is to omit 140 also but since that is what existed all along in S9, Netscape6.21 uses this name and N621 needs guarantee that this name will exist in future releases of java 1.4 plugin.

Typical solaris approach always provides a library name that is version neautral and then if there is a compelling need then the new version can be libjavaplugin_oji140.so.<N>. Making sure that the version neautral name is pointing to this one now.
