Hi guys,
I have an Android application to connect via jRDC2 to Ubuntu Server.
Application runs OK, until I use it on new server.
Here are the codes in B4A to connect to database
Error Messages are :
ResponseError. Reason: com.mchange.v2.resourcepool.TimeoutException: A client timed out while waiting to acquire a resource from com.mchange.v2.resourcepool.BasicResourcePool@5b5cba25 -- timeout at awaitAvailable(), Response: <html>

Java version on old Server that runs OK is Oracle Java 1.8.0_171.
Java version that raised error on new server is OpenJdk 17.0.12.
Could it be the error cause by different Java version?
