[eclipselink-dev] Updated patch for Bug Bug 270843 - Possible deadlock s

["Andrei Ilitchev" <andrei.ilitchev@xxxxxxxxxx>]

https://bugs.eclipse.org/bugs/show_bug.cgi?id=270843

The original patch was updated to handle separately case of
preallocationSize==1: it doesn't require neither locking nor checking 
already
allocated values. The only drawback: if after session.login the 
preallocation
value was changed to 1 the values already allocated may end up being not 
used.

Please send any feedback you may have.

Thanks,

Andrei
