Daniel Estermann commented on ARIES-1715:
-----------------------------------------
I have found a workaround for this but it's pretty ugly. This:
{code:java}
@PostConstruct
public void init() {
//... do something with an entityManager
}
{code}
...changed to:
{code:java}
@PostConstruct
public void init() {
new Thread() {
@Override
public void run() {
Bundle b = FrameworkUtil.getBundle(MyService.class);
BundleContext bc = b.getBundleContext();
ServiceTracker<MyService, MyService> tr = new
ServiceTracker<>(bc, MyService.class, null);
tr.open();
try
{
MyService self =
tr.waitForService(TimeUnit.SECONDS.toMillis(15));
self.updateProcessingItems();
}
catch (InterruptedException e) { //... }
}
}.start();
}
public void updateProcessingItems() {
//... do something with an entityManager
}
{code}
...should do the job.
> Blueprint doesn't apply interceptors for the init-method.
