OS - Linux Redhat 7.2, 7.3
Build - Mantis SWAT build-04

Steps to reproduce -

Install the j2sdk-1.4.2/j2re1.4.2 rpm bundles from -
/net/mizu/usr/re/jdk5/jdk1.4.2/bundles/linux-i586/b04-2002-10-23

During installation, the following error message is thrown

Preparing packages for installation...
j2sdk-1.4.2-beta
/var/tmp/rpm-tmp.20519: line 23: 17634 Aborted $UNPACK_CMD $srcFile $dstFile
Error: unpack could not create /usr/java/j2sdk1.4.2/jre/javaws/javaws.jar. Please refer to the TroubleshootingSection of the Installation Instructions on the download page.error: execution of %post scriptlet from j2sdk-1.4.2-beta failed, exit status 1

The installation completes and j2sdk1.4.2 is created under /usr/java.

Go to /usr/java/j2sdk1.4.2/jre/bin, and invoke the Plugin Control Panel. The Control Panel does not come up, and the following exception is thrown -

Exception in thread "main" java.lang.NoClassDefFoundError: sun/plugin/panel/ControlPanel

This is because javaplugin.pack has not been unpacked under the lib directory, and hence there is no javaplugin.jar
