We have an application that uses the ecsjtapi library version 7.0.0.64. We recently upgraded to Java 11. After that, we get an error:

2023-05-16 10:33:09,627 [ProviderInitialization] ERROR com.avaya.jtapi.tsapi.impl.core.TSInitializationThread -
java.lang.IllegalArgumentException
        at java.base/java.util.concurrent.ThreadPoolExecutor.setCorePoolSize(ThreadPoolExecutor.java:1535)

        at com.avaya.jtapi.tsapi.impl.core.TSInitializationThread.run(TSInitializationThread.java:67)

Does this mean that we need a different version of the ecsjtapi library, or is it something else?

Thanks.

Hi Jeff,

did you try with the Devconnect JTAPI forum ( https://www.devconnectprogram.com/forums/forums/show/10.page ) ?

I did not. Not sure how I missed that forum. I'll post over there. Thanks!

Java 11 is not supported with the JTAPI R7 Client
JTAPI R7 client has been out of support since 2018
JTAPI Client R7 was only tested against Java R8.
