Problem searching for local JVMs

Post by Paul Gellissen »

Hi,

i have noticed that on my machine the function searching for local JVMs does not work. I have installed the latest AdoptOpenJDK version(8.265) and and older Oracle JRE. Whenever I trigger the search for local machines nothing gets found. I have tried starting the OWS settings console as an admin but that does not help either. Attached is the debug log file for the machine containing an error showing during the search for local JVMs.

PS:
Consider enabling the upload for .log files in this forum.

Can you please also provide us with the path of the directories where you have installed the JVMs

Hi

I presume you are using OWS 1.2.1 on Windows.

There is an exception in the logs:

Code: Select all

[ITW-APP ][2020-10-08 16:23:08.707 MESZ][ERROR][sun.nio.cs.StreamEncoder.writeBytes(StreamEncoder.java:221)] Exception in thread "ows-pool-1" java.util.ServiceConfigurationError: com.openwebstart.jvm.localfinder.RuntimeFinder: Provider com.openwebstart.jvm.localfinder.MacRuntimeFinder not a subtype
Ideally you should see a log message as follows:

Code: Select all

I will investigate and come back to you.

Hi Karakun,

we are running into the same problem here. OWS 1.2.1 on Win10 1909. We can't find our locally installed Amazon Corretto packages anymore. Installation paths are:

C:\Program Files (x86)\Amazon Corretto
C:\Program Files\Amazon Corretto

As we are in the middle of the internal package creation this is going to be a showstopper for our rollout. Do you guys know when and how this is going to be fixed?

Regards!

Thanks for reporting this problem. It is some problem with ServiceLoader which is not always reproducible.

We decided to fix it by doing away with the ServiceLoader.

We are making a bug fix release OWS 1.2.2. We will announce as soon as it is out.
