Simon Nash resolved TUSCANY-1347.
---------------------------------
Resolution: Fixed
Fix Version/s: (was: Java-SCA-Next)
Java-SCA-1.2
The NPE no longer occurs. With EchoServiceImpl.asyncEcho() updated to use the
correct APIs, this program seems to be working as implemented. The JUnit test
case claims that an error has occurred because no exception was thrown from the
async invocation, but I don't understand why this is expected.
If you think there is still a problem here, please reopen the JIRA with a
description of what results are expected and why.
Here is the code I used in my version of the EchoServiceImpl.asyncEcho() method:
public String asyncEcho(String input) {
AsyncEchoService asyncEchoService;
ServiceReference<AsyncEchoService> serviceRef =
context.getServiceReference(AsyncEchoService.class, "asyncEchoRef");
asyncEchoService = serviceRef.getService();
asyncEchoService.echo(input);
int count = 0;
while (_result == null & count < 10) // wait ten seconds max
{
System.out.println("while loop: _result " + _result);
try {
Thread.sleep(1024);
count = count + 1;
} catch (InterruptedException e) {
}
}
return _result;
}
