Hi,
we have some trouble debugging this...
As far as i understand the code, InternalPlatform::GetInstance() is a
singleton (after Meyers, static).
So it shouldn't be possible that there is another InternalPlatform
instance created for a second time. This happens for the first plugin,
'system.bundle'.
After executing the singletons instance's getter, code:
--->
InternalPlatform* InternalPlatform::GetInstance()
{
Poco::Mutex::ScopedLock lock(m_Mutex);
static InternalPlatform instance;
return &instance;
}
<---
...the line 'static InternalPlatform instance;' executes the constructor
of InternalPlatform again. This leads internally to execution of the
base class constructor (Poco::Application), which calls setup(); There,
the assertion fails, because the InternalPlatform has already been
instantiated.
This second call to the InternalPlatforms constructor chain happens in:
--->
void org_blueberry_osgi_Activator::start(ctkPluginContext* context)
line 38:
InternalPlatform::GetInstance()->GetBundle("system.bundle").Cast<SystemBundle>()
<---
The CallStack is attached. Anyone has an idea what is going wrong?
Regards,
Thomas
