From my experience, JVM in the database gets very little use. I am not sure why is that, Java is the new COBOL and everybody is doing applications in Java. OO programming which is very useful and very modern, as you can see here:

is mostly done in Java and Python. Just about everybody is doing Java. However, the Java OO orientation might be the answer why people don't use it in the database.  When you write a trigger, a function or a procedure and store it in the database, you want it to be as streamlined and efficient as possible. You don't want all that OO chaff that defines strings, regular expressions or alike. PL/SQL which is mostly procedural in nature, is far better suited for DB work than all that OO clutter in Java. Having said that, I am sure that in the long run, Java will prevail. Databases on Millennium Falcon will probably run Java internal procedures, which may bring into question completing the Kessel run in less than 12 parsecs. However, at that point I will have 6' of earth on top of me and will not care.
