EXCEPTION_ACCESS_VIOLATION in HotSpot Virtual Machine:

[Bruce Petro]

I'm hitting the error shown below in my code in the following manner...

Working with a fairly complex object composed of several component objects - so quite a bit of memory probably...

a) Editing an object, saving the results, then without clearing the screen, request the another object via RPC with the intention of refilling the screen with the new fresh values for the new object.  When the RPC send attempts to happen, the browser (IE or hosted) vanishes. If I'm in hosted mode then Eclipse console contains the error and reference to a detailed error file. (attached).

b) Interesting!  If instead of requesting a new object to edit, I instead go to the menu and re-draw the screen from scratch - then no error occurs.  

Theories:

a) We're running out of memory and I need to up the memory (can that be done in IE browser running javascript?)

b) The UI and its "ties" to the data module object is getting totally confused by swapping the model out from under it.

The detail file included seems to be hinting at memory, but I may be reading it wrong. Any ideas from anyone out there?  If it is memory, how does one go about increasing memory in a running javascript application?

I had the same issue with GWT 2.0.0-rc1 and rc2 with JDK1.5 update 22.
I switched to JDK 1.6 and the problem went away. I only had this
happen in "development" mode, and consistently so.

Thanks!  I cannot switch java versions but I can work on memory issues in general.  

BTW: I was sloppy. I failed to mention I'm working in 1.6.4 version.  Also, if others are searching this in the future, I believe I should abandon the UI -> model links as an issue. The reason is the detail file indicates memory AND debugging, the crash consistently comes at the moment of the send to the RPC for the next object and I would presume RPC send cycles are a high-point in memory and resource usages.
