Ted Yu commented on HBASE-9754:
-------------------------------
I saw the same number of findbugs warnings in:
https://builds.apache.org/job/PreCommit-HBASE-Build/7538/console
which was for HBASE-9748
I think the cause was the following:
{code}
[INFO] Compiling 44 source files to

# There is insufficient memory for the Java Runtime Environment to continue.

> Brought up by [~vrodionov] and [[email protected]].
> Currently we use ThreadLocals to communicate the current readpoint between a
> RegionScanner and the Store\{File}Scanner's down the stack.
> Since ThreadLocals are not cheap we should consider whether it is possible to
> pass the readpoint through the call stack instead.
