        Description


        Before Java SE 7 Update 6, if both 32-bit and 64-bit Java SE 7 were installed,
        the following behaviour was obtained on 64-bit Windows:
        64-bit Internet Explorer launched 64-bit Java Web Start,
        32-bit Internet Explorer launched 32-bit Java Web Start.

        Beginning with Java SE 7 Update 6 there was a change in behaviour:
        if both 32-bit and 64-bit Java SE 7 are installed,
        64-bit Internet Explorer launches 64-bit Java Web Start,
        32-bit Internet Explorer launches 64-bit Java Web Start as well on 64-bit Windows.

        Now this raises the following problem:
        if both 32- and 64-bit Java SE 7 are installed, it breaks 32-bit-only Java Web Start applications,
        e.g.: Java Web Start applications, that use 32-bit native libraries, and that don't have a 64-bit representation of these native libraries.
