Redis Extension Cast Error

Description

We are currently using Redis Extension ( redis.extension-2.9.0.4-BETA ) to manage the Session across multiple instances of Lucee.

After Redis failover, Lucee starts throwing errors and the only solution right now is to terminate the Lucee instance.

Heres the stack trace:

java.lang.ClassCastException: [B cannot be cast to java.lang.Long at redis.clients.jedis.Connection.getIntegerReply(Connection.java:265) at redis.clients.jedis.Jedis.expire(Jedis.java:315) at lucee.extension.io.cache.redis.AbstractRedisCache.put(AbstractRedisCache.java:131) at lucee.runtime.type.scope.storage.IKHandlerCache.store(IKHandlerCache.java:54) at lucee.runtime.type.scope.storage.IKStorageScopeSupport.store(IKStorageScopeSupport.java:415) at lucee.runtime.type.scope.storage.IKStorageScopeSupport.getInstance(IKStorageScopeSupport.java:198) at lucee.runtime.type.scope.ScopeContext.getCFSessionScope(ScopeContext.java:667) at lucee.runtime.type.scope.ScopeContext.getSessionScope(ScopeContext.java:505) at lucee.runtime.PageContextImpl.sessionScope(PageContextImpl.java:1389) at lucee.runtime.PageContextImpl.sessionScope(PageContextImpl.java:1383) at lucee.runtime.interpreter.VariableInterpreter.scope(VariableInterpreter.java:655) at lucee.runtime.interpreter.VariableInterpreter.getVariableEL(VariableInterpreter.java:221)

Reading a little bit online looks like its related to the re-use of a closed connection, but I can be wrong:

Could you please try this with the latest Redis extension? And report me back here. It could be helpful to improve the ticket status.

Miguel Targa 3 September 2020 at 16:37

Yes, used in multiple instances.
And all use the same version.

Michael Offner 3 September 2020 at 16:32

is Redis used by multiple instances? if so are all using 2.9.0.10-RC?

We are still having issues, here's the pool config:

i have reviewed the extension code and the jedis code to better understand the problem and i have done some improvements with the following version.

That version make sure we have never 2 pools open and that we handle better exception while loading a connection.
