             Summary: Refactor Platform remote job execution routine for 
PlatformClosureJob
                 Key: IGNITE-5111
                 URL: https://issues.apache.org/jira/browse/IGNITE-5111
             Project: Ignite
          Issue Type: Task
          Components: platforms
    Affects Versions: 1.9
            Reporter: Igor Sapego
             Fix For: 2.1


If we take a look at 
{{org.apache.ignite.internal.processors.platform.compute.PlatformClosureJob}}

We can see code as follows:
{code}
createJob(ctx);

try (PlatformMemory mem = ctx.memory().allocate()) {
        //...
        ctx.gateway().computeJobExecute(mem.pointer());
        //...
}
finally {
        ctx.gateway().computeJobDestroy(ptr);
}
{code}
It also seems like {{ptr}} is not used anywhere, so it looks like this can be 
replaced with single call to native code instead of three. We also can get rid 
of the handle allocation for the closure object in platform code.
