Java Plugin for JDK 6 u2 b01 doesn't work on RHEL 5 x86 with the mesage:

java.lang.UnsatisfiedLinkError: /export/JDK/jdk1.6.0_02/jre/lib/i386/libdeploy.s

the code problem is:

ldd libdeploy.so
        linux-gate.so.1 => (0x006e8000)
        libc.so.6 => /lib/libc.so.6 (0x00d58000)
        libstdc++.so.5 => not found
        libm.so.6 => /lib/libm.so.6 (0x00613000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00af2000)
        /lib/ld-linux.so.2 (0x4dd10000)


Plugin still works on RHEL 4
