> During VM creation, Harmony will parse all class libraried defined in bootclasspath.properties under jre/lib/boot directory. However, not all class libraries will be used in the lifetime of java applications. That means, it is not necessary to open and resolve all these class libraries.
> In this patch, I implement the on-demand jar parsing, which only loads and parses required jar.
