Vladimir Rodionov updated HBASE-12090:
--------------------------------------
Attachment: HBASE-12090.2.patch
1. I fixed compilation errors by changing import orders
2. The previous version introduced huge performance degradation. 45 sec vs 39
original patch. There is something wrong with HotSpot compiler when it has to
optimize static-class->static-class->static-method invocation (I bet it does
not do inlining properly)
This patch has original performance and no compilation errors.
