Ha-ha that code was buggy anyway :-) As I've already said we do need
filter Thread.runImpl frames for java threads created by calling
Thread.start method. Elena, you've fixed that code once, probably, you
wish to fix it once again? :-)
Thank you

Actually, the code should be fixed rather than commented out in the
following way:

bottom

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")

for (; --size;) {
method = frames[size - 1].method;
assert(method);
if ((strstr(method->get_class()->name->bytes,

break;
}
}
}
ASSERT(size >= skip, "Trying to skip " << skip
<< " frames but there are only "

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,

Sorry I didn't mention about this before. After these changes I
could
sucessfully start the ActiveMQ.
Before I have the following error:

Hello,
I'm observing the same problem - ActiveMQ can't
start -
on
DRLVM
+
Classlibrary build 442240 .
The problem I see first is that in
<classlib
root>\modules\luni\src\main\native\launcher\shared\main.c
in function 'static int invocation' after call
'createVMArgs'
variable
'mainClassJar' contains garbale while in the very
end of
'static
int
createVMArgs' it contains valid string
'org.apache.harmony.kernel.vm.JarRunner' . If we
comment
out
'hymem_allocate_memory' in that function:
if (isStandaloneJar)
{
if (useDefaultJarRunner == 0)
{
//:::commented out:::: mainClassJar =
hymem_allocate_memory (50);
if (mainClassJar == NULL)
the application will crash a little later. Note: we
can
comment
this
out because memory for mainClassJar is already
allocated
in
the
calling method.
I believe that the general problem is that contents
of
memory
alocated
with hymem_allocate_memory get somehow broken on
exit
from a
method.
