Uwe Schindler commented on LUCENE-2556:
---------------------------------------
There is also no problem with reusing the cloned attribute, as ArrayUtils grows
the array correctly also in that case. So you can still apend stuff as usual,
with a *small* perf penalty maybe.
I think I will commit this later this evening to trunk and 3.x. Merging is
little harder because of sophisticated backwards layer in 3.x. :-)
