Hi, I am using BaseX 6.5. I am running into a server crash. Could you fix it ? I see the following error where I run my server:
Exception in thread "Thread-4" java.lang.NullPointerException
        at org.basex.query.up.Updates.size(Updates.java:110)
        at org.basex.query.QueryProcessor.updates(QueryProcessor.java:234)
        at org.basex.server.QueryProcess.initInfo(QueryProcess.java:162)
        at org.basex.server.QueryProcess.close(QueryProcess.java:139)
        at org.basex.server.ServerProcess.query(ServerProcess.java:291)
        at org.basex.server.ServerProcess.run(ServerProcess.java:128)
Also, please find attached a copy of the complete log file. Thanks, Sony

Hi Godmar, that bug was pretty easy to fix, and I have no idea how the superfluous downcast passed all our tests. It was introduced in version 6.2.8. Here's the fix: https://github.com/BaseXdb/basex/commit/9fd2fcd ;-) Do you need a new .jar file? Cheers Leo
