Nathan Beyer commented on HARMONY-5843:
---------------------------------------

I meant, why is it called 'lazy.test'?

> On class-unloading scenarious, DRLVM easily hits a bunch of asserts in gc_gen. Most typical asserts are:
>     [junit] Assertion failed: obj && obj->vt_raw, file c:\users\avarlamo\trunk\working_vm\vm\gc_gen\src\common\gc_for_class.h, line 207
>     [junit] Assertion failed: address_belongs_to_gc_heap(addr, gc), file c:\users\avarlamo\trunk\working_vm\vm\gc_gen\src\thread\../gen/gen.h, line 152
>     [junit] Assertion failed: vm_object_size(obj) != 0, file c:\users\avarlamo\trunk\working_vm\vm\gc_gen\src\common\gc_block.h, line 146
> These asserts fire intermittently, may be reproduced in any mode including interpreter and on any platform (yet on different machines a particular assert happens more often than others).
> To reproduce, run lazy.test suite:
> working_vm$ ant lazy.test
> For convenience, there is standalone launcher org.apache.harmony.vm.test.lazyresolution.StressTest which can vary stress load, e.g.:
> working_vm$ cd build\windows_x86_msvc_debug\tests\lazy.tests\classes
> classes$ java -cp .;junit.jar -Dlazy.test.iterations=100 -Dlazy.test.threads=10 org.apache.harmony.vm.test.lazyresolution.StressTest
