beanshell - Deadlock issue

Has anyone got any experience of having deadlocks with beanshell? This is something we have been encountering recently in our production system where script execution is blocking other threads, due to it's lock on classloading via tomcat. The following is the stacktrace for the lock owner in thread dump:
"Thread-64" : 150 : BLOCKED : cpu=37812500000 : cpuLoad= 0.0

I see that Groovy is a more popular choice for Java scripting, but I haven't seen many posts where it says that bsh can cause deadlocks.
It would be good to get some ideas from SO users.
Regards,

There's a fix for one dead lock in GUI does not start in Java 8 found in Beanshell (almost latest) version 2.0b5.
You can open a new issue in Beanshell project.
It may be connected to ClassManagerImpl:
Bsh has a multi-tiered class loading architecture. No class loader is
created unless/until a class is generated, the classpath is modified,
or a class is reloaded.
Note: we may need some synchronization in here

Cassandra NoHostAvailableException: All host(s) tried for query failed in Production

We have 10 Cassandra nodes in production running Cassandra-2.1.8. We recently upgraded to 2.1.8 version. Previously we were using only 3 nodes running Cassandra-2.1.2. First we upgraded the initial 3 nodes from 2.1.2 to 2.1.8 (following the procedure as described in Upgrading Cassandra). Then we added 7 more nodes running Cassandra-2.1.8 in cluster. Then we started our client programs. For first few hours everything worked fine, but after few hours, we saw some errors in client program logs like

Now, I double checked the Firewall (as suggested in few posts), ports, timeouts in client as well as nodes and they all are correct.
I am also not closing the connection anywhere in between. I am using batch queries with batch size of 1000 and the queries are update queries updating counters in my table with three columns
entity , twfwv , cvalue
where entity and twfwv columns are text and primary key and cvalue is counter column.
I even restarted all my nodes (because this trick helped me in my dev environment when I faced the same exception) but its not helping. Please suggest what can be the probable problem here.

My issue was resolved by checking the errors collection of NoHostAvailableException as advised by Olivier Michallat in the comments. For me it was the protocol version on the cluster configuration. Mine was null, setting it to 3 fixed the problem.

My issue was resolved by removing/using a property to set or unset the custom load balancing TokenAwarePolicy my connection was using, and relying on the default.
Specifically, I was trying to get a local spring boot app talking to a single dockerized Cassandra instance.
Cluster.Builder builder = Cluster.builder()
.addContactPoints(cassandraProperties.getHosts())
.withPort(cassandraProperties.getPort())
.withProtocolVersion(ProtocolVersion.V4)
.withRetryPolicy(new LoggingRetryPolicy(DefaultRetryPolicy.INSTANCE))
.withCredentials(cassandraProperties.getUsername(), cassandraProperties.getPassword())
.withCodecRegistry(codecRegistry);
if (loadBalanced) {
builder.withLoadBalancingPolicy(
new TokenAwarePolicy(DCAwareRoundRobinPolicy.builder().withLocalDc(localDc).build()));
}

what do these neo4j 2.0.1 exceptions mean?

We embed Neo4j 2.0.1 community edition on Linux 64 and JRE 1 7 51 in a multi-threaded application.
Intermittently (rarely) we get following exceptions when we delete a Relationship and execute a cypher within same transaction, respectively.
Should we be using pessimistic locks for these deletes? what do these exceptions mean?

it happens such kind of error for my resin webserver, I have several resin servers and only one server throw out such error suddenly.

remove the resin-data diretory,then restart resin

It looks like you might have a database corruption there ...
Possibly related Resin bug report: http://bugs.caucho.com/view.php?id=4956
The resolution for the bug report says "Fixed", so you should probably check your Resin installation is up to date.

Changes to a Lotus Domino xpages java application do not propagate to the server

Using Lotus Domino 8.5.2 Fixpack 3
The title sums it up. I have an xpages application that uses java. It seems that any java changes I make, never become visible on the server. It sounds a dead ringer for a cache issue of some kind. The application runs on the server and I see System.out.println statements in the server log, but do not any of the changes I've made to those statements or any new ones I've added.
The code is set to Rebuild Automatically. Still, it never looks like the server sees the changes. Is there some special way I need to build the database (aside from the typical Rebuild All)? Do I need to reset or restart some process on the domino server for it to see the changes?
Any thoughts or ideas would be greatly appreciated.
EDIT 1
I'm returning to this project and, hence, this question. The specific error message I'm getting is:

I've tried unchecking automatic build and doing a clean --> rebuild all. I've tried signing the nsf again. I've ensured that I'm on the acl. And, as recommended, I've tried the
restart task http
Command via live console. No matter what I do I'm getting this error. The odd thing is that this project is just a copy --> paste (with rename) of another one that works fine. So, the project works...until I change and recompile...
The log that exception above points to wasn't very helpful. It reads:

As ever, penny for your thoughts.
Also, thank you all for your feedback. I'm sorry I've been away for a bit and neglected this question. I really would like to figure this out.

You didn't mention Project -> Clean so try that first.
I had once similar problem that was caused by an underscore in class or package name.
If the problem exists also for XPages then it's a a general build problem. This can occur at least when developers with different Designer and/or ExtLib versions modify the application. When I had this problem the only way to fix it was to create a new application and copy paste everything there. In our case the other developer never had the problem.

This is just silly. My src folder wasn't on the build path. That was causing all the issues.
