500 elements limit for arrays in "Object explorer"

by **wantosz** » Tue Sep 04, 2007 8:38 pm

Let say I have an array of size 600. I would like to be able to inspect, for example, the last element. The "Object explorer" lists first 500 only and shows "and more..." below, but there appears no way for me to either advance to next 500 or view element at specific index. Am I missing something?

(PS. I am viewing an HPROF dump)

Hello,

This number is hardcoded.

We'll add ability to advance to next 500 or similar means to browse more elements in future version.

Could you please provide more detail on why you need to manually browse content of such big array. I hope I'll be able to suggest suitable workaround and/or an alternate approach.

Best regards,
Anton

I have same issue.

I have two lists of instances for a given class in two snapshots. The lists are about 4800 items long. They differ in ONE instance. I need to know which one it is and all I get is "and more..." at the end of the list.

You can try "Memory | Retained Objects..." (Shift+F4) for each of the lists, and then analyze content of a new tab which will open.

Hi !

Any news on this since 2007 ? ;-)

We are currently trying to address the memory retention issue that using File.deleteOnExit() causes (cf. https://bugs.openjdk.java.net/browse/JDK-4872014) and we would like to export all the strings that the LinkedHashSet of java.io.DeleteOnExitHook holds, in order to figure out which file name patterns are the most offending and whether a punctual fix would be enough in the short term.

As of YourKit 2016.02-b43, the "Open collection elements in a new tab" link only shows the 500 first (?) elements, with no way to display more elements, or export them, etc.

How could we do that (or something similar) ?

Thanks in advance for your answer !

There is no dedicated UI for this purpose yet, sorry.

As a workaround, please specify the property (with even bigger value, if necessary) -Dyjp.max.objects.to.show=100000 in <user home>/.yjp/ui.ini

Seems to work like a charm, and a parameter is fine enough : thanks !
