Kirill Shirokov commented on IGNITE-6915:
-----------------------------------------
Note that the fix substantially minimizes the probability of this bug. Still,
under extremely rare circumstances two tables in the same cache can still
erroneously share b+tree. This can happen when both Optimized Marshaller and
persistence is enabled, and two different value types for which the tables are
created are:
1) both Externalizable
2) have the same simple name
3) have the same first letters of the packages
4) have the same hash code of the fully qualified class name (see
H2TreeIndex.mangleClassName() for details)
or
simple class name length is close to 250 characters (see
MetadataStorage.MAX_IDX_NAME_LEN)
