The biggest object in the heap dump is an ArrayList that contains 540 thousand items of type com.mysql.jdbc.ByteArrayRow (size of the list is 649 MB).

So the problem is probably somewhere in MySQL JDBC driver or NetBeans Database support.

Did you run some SQL query? Can you please try to reproduce the bug?
If you can reproduce it, please try toggling Scrollable Cursors support (Services tab -> Databases -> right-click the DB connection -> Properties -> (un)check Use scrollable cursors).

Closing for now. Please provide any additional information and reopen this issue. Thank you.
