Why is /usr/lib/default-java pointing to the “wrong” jdk?

I got a linux mint pc with openJDK 1.11 pre-installed. I installed the openJDK 1.8. package and set the default java (sudo update-alternatives --config java) to it. All is working fine (java -version outputs the correct java version). Now that I try to use maven, in my attempt to change JAVA_HOME (because it was not pointing to the correct location - this is working now, too), I saw a directory called default-java (/usr/lib/jvm/default-java) which is a symlink to the original 1.11 JDK, even though I am not using it at all.



Can someone tell me what that means, if that is a problem and if I should change it?



Thanks in advance!

          SQL update select statement

          Image
          0 I'm trying to update an entry in my database (postgresql). I'm having a problem with updating the query: INSERT INTO prices (price, product_id) SELECT product_price, commn_id FROM products_temp as prod WHERE NOT EXISTS (SELECT * FROM prices od WHERE prod.commn_id = od.product_id) OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) Query works fine when i delete: OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) So it seems to me that it's looping through this operation. My question is, how can I fix it? sql postgresql
