Description Christopher Deckers CLA 2011-04-30 13:57:53 EDT 
Build Identifier: SWT 3.7M7

When more than one native control is present on the UI, disposing them crashes the VM. The native controls I am using are Browser widgets with default runtime (Safari).

Result in console: Invalid memory access of location 0x20 eip=0x98843ed7

VM options: -XstartOnFirstThread -d32


Reproducible: Always

Steps to Reproduce:
See attached test case.

Tesrt case showing the crash

There is a constant that allows to test with other number of component. With 1, a component can be added/disposed/added/etc without any issues.

I tried this with 4.3 build and do not see any crash. The snippet works fine, though a NPE is printed in the console.
Can you pls. try this with the 4.3 build and see if it crashes?

Closing report as it is not reproducible with 4.3. Please reopen if you can reproduce the crash.
