Q: 

OQL for finding new objects only in heap dumps?

Does anyone know the OQL syntax for finding new objects only in a heap output? I can't find good documentation on OQL options, sun even has an example of new-only output without sample syntax of the query that generated it.What I've done is

  • Created a set of heaps with jhat
  • Served them up with jmap -baseline, which marks objects not in both heaps as "new".
  • browse jhat
  • scratch head

At least this page has some examples: jstack-jhat-Object-Query-Language-OQL.html

Eclipse memory analyzer is THE tool when it comes to interpreting results of a heap dump. See http://stackoverflow.com/questions/1279346/why-doesnt-the-baseline-option-of-jhat-work
