Good afternoon.
Linux openSUSE Tumbleweed
VERSION_ID="20230902"
apache-karaf-4.4.4
I have performed the following test:
I download apache karaf 4.4.4.tar.gz and extract it.
I modify setenv with the following data:
export JAVA_HOME=/home/desarrollo/tools/jdk11.0.17
export EXTRA_JAVA_OPTS=-Djava.locale.providers=COMPAT,CLDR
I run "apache-karaf-4.4.4/bin/karaf" and inside the console, I execute:
karaf@root()> feature:repo-add
mvn:org.apache.karaf.examples/karaf-jpa-example-features/LATEST/xml
karaf@root()> feature:install karaf-jpa-example-datasource
karaf@root()> feature:install karaf-jpa-example-command
karaf@root()> feature:install karaf-jpa-example-provider-ds-hibernate
karaf@root()> booking:add Doe AF520
karaf@root()> booking:list
ID │ Flight │ Customer
────────┼────────┼─────────
1 │ AF520 │ Doe
In the karaf.log, I get:
2023-10-09T23:06:27,402 | WARN | features-3-thread-1 |

I close with Ctrl-D.
I run again:
apache-karaf-4.4.4/bin/karaf
karaf@root()> booking:list
ID │ Flight │ Customer
────────┼────────┼─────────
karaf@root()>
(No data)
And in karaf.log, I have the same error.
