[jbosstools-issues] [JBoss JIRA] (JBIDE-11682) Richfaces 3.3.0.Beta1 and later: Java reference search hangs

Alessandro Colomba commented on JBIDE-11682:
--------------------------------------------

Thank you, I tried again with different memory settings and making sure to clear the workspace.

The latest nightly (Apr 30th) does indeed make a huge difference. With -Xmx1500m the index took about 5 mins to generate (after which searches are quite fast.) With -Xmx2000m it took a little less, with the heap reaching about 1.7GB during indexing.

I went back to the previous nightly (Apr 25th), before your commits, and tested with -Xmx2500. The search eventually went on to use all available heap space, and after 15 minutes it was still running.

In summary, as you said the search does not hang, but it's very resource-intensive. By comparison, we have been able to run Eclipse with -Xmx768m for a long time, despite the size of the codebase. Doubling the heap space for this one feature would not be ideal.

Is there anything else that could be done to reduce memory usage further? Or, would it be possible to avoid for a reference search to optionally avoid scanning XHTML files altogether?

Thank you both for all your work.

> Given a vanilla install of Eclipse/STS on either Mac/Windows plus the Richfaces plugin, a Java reference search (cmd/ctrl-shift-g) on a method results in:
> - The method references being found and displayed in the Search pane
> - The search continuing indefinitely, slowly allocating memory until the heap is exhausted.
> A stack dump of the process is attached.
