Subject: [PATCH] Fix race condition on UpgradeData.BlockFixers class init
|
|
|
|
The CHUNKY_FIXERS field is modified during the constructors
|
|
of the BlockFixers, but the code that uses CHUNKY_FIXERS does
|
|
not properly ensure that BlockFixers has been initialised before
|
|
using it, leading to a possible race condition where instances of
|
|
BlockFixers are accessed before they have initialised correctly.
|
|
|
|
We can force the class to initialise fully before accessing the
|
|
field by calling any method on the class, and for convenience
|
|
we use values().
