At the time this was re-added, there was concern around how the JIT would handle the system property that enabled it. This shouldn't be a problem, and as such we no longer need to block access to it. The Vanilla Method Profiler will not provide much to most users however there is no harm in providing it as an option. For most users, the recommended and supported method for determining performance issues with Paper will continue to be Timings.

Subject: [PATCH] use CB BlockState implementations for captured blocks
|
|
|
|
When modifying the world, CB will store a copy of the affected
|
|
blocks in order to restore their state in the case that the event
|
|
is cancelled. This change only modifies the collection of blocks
|
|
in the world by normal means, e.g. not during tree population,
|
|
as the potentially marginal overheads would serve no advantage.
|
|
|
|
CB was using a CraftBlockState for all blocks, which causes issues
|
|
should any block that uses information beyond a data ID would suffer
|
|
from missing information, e.g. Skulls.
|
|
|
|
By using CBs CraftBlock#getState(), we will maintain a proper copy of
|
|
the blockstate that will be valid for restoration, as opposed to dropping
|
|
information on restoration when the event is cancelled.
