JDK-6331661 - jhat: reduce memory by preferring iterator/enumeration instead of arrays
Description
jhat reads heap dump and creates object model out of that. For large dumps, jhat consumes lot of memory. Large primitive array content could be read lazily -- this could avoid some memory consumption.
Comments
EVALUATION Reading large primitive arrays lazily should help in reducing memory requirement.
