RFR (XXS): 8040792: G1CodeRootChunkManager::static_mem_size returns the wrong size

[Thomas Schatzl]

Hi all,

  can I have reviews for this tiny change that fixes one error that
Mikael Gerdin found in the review for "8038930: G1CodeRootSet::test()
fails with assert(...)" just a few minutes after I pushed the change?

It's about changing the following line in G1CodeRootSet.cpp:

  86 size_t G1CodeRootChunkManager::static_mem_size() {
  87   return sizeof(this);
  88 }

to

  87   return sizeof(*this);

Testing:

Thanks,
