Actually, the code should be fixed rather than commented out in the
following way:
//--size;
// skip the VMStart$MainThread.runImpl() if it exists from the bottom
// of the stack along with 2 reflection frames used to invoke method
main
static String* starter_String =
genv->string_pool.lookup("java/lang/VMStart$MainThread");
Method_Handle method = frames[size - 1].method;
assert(method);
if (!strcmp(method_get_name(method), "runImpl")
&& method->get_class()->name == starter_String) {
for (; --size;) {
method = frames[size - 1].method;
assert(method);
if ((strstr(method->get_class()->name->bytes,
"java/lang/reflect"))
== NULL) {
break;
}
}
}
ASSERT(size >= skip, "Trying to skip " << skip
<< " frames but there are only "
<< size << " frames in stack");
The fix has been submitted in HARMONY-1431 which depends on HARMONY-1363.
As for Eclipse's silent exit, please try to find what has happened in the
eclipse/configuration/*.log files.
Thanks,
