On linux, When attempting to wrap Oracle's 32-bit java plugin JRE version 1.6.0.24 (aka libnpjp2.so), nspluginwrapper reports a missing dependency (__gxx_personality_vo). The problem arises because the plugin expects the standard C++ runtime library to be loaded (stdlibc++.so). This problem could arise with other plugins as well.
It is worth noting that this patch will permit users to run the popular WebEx meeting client on 64-bit browsers. This client requires native 32-bit libraries on linux, and therefore will not run on a 64-bit JVM.
With the following patch, nspluginwrapper will create a wrapper for 32 bit Java without complaint. The JRE appears to execute correctly. My only discomfort with it is that I have hard-coded version 6 of the standard C++ library. It may be more appropriate to allow the most recent version to be selected.
