Failed to start pojo cache with JDK 1.6

[ctof]

Hi

I try to start my application which need to be compiled with jdk 1.6 (due to external 1.6 lib dependencies) and it fails when i start the second client (during the state synchronization).
I use PojoCache 2.0.0-RC1

I have made a test by removing my 1.6 code dependencies,compile and run my sample under 1.5, and all works fine.

Any idea ?
Thx
Christophe

Hi

Any idea ?
Nobody is using JBoss with jdk 1.6 ?

[manik]

Not as far as we know, so far.

This is something we will investigate though.

I too have run into this problem using JDK 1.6 and it presents a major problem for me. I'm currently evaluating various caching tools for our product, and we require JDK 1.6 and going to back to JDK 1.5 is not an possible for us.

It works fine when multiple nodes are brought up before anything is put into the cache.

Is there any JIRA issue that tracks this compatibility problem?

Anyway, I think the root cause in my case is the ClassNotFoundException below:

I have the same problem as ctof with JDK 1.6. Is any solution found?

FYI, we do have cruise control running the JBoss Cache TestSuite with JDK 1.6 as well, just that we haven't spent much time looking at why things fail under 1.6.

http://cruisecontrol.jboss.com/cc/buildresults/jboss-cache-testsuite-jdk16

Anyway, stuff that will be cleaned up by CR3.

Hello


I'm not sur (my latest test are 2 month ago) but this pb occurs only when you start 2 different JVM (and try to synchronize them). I remember me that when you run test with 2 caches in the same JVM, all works fine. Maybe there is a JGroups optimisation for exchange in memory ?

it's to be check, i'm actually busy on another job, but when i'll have more free time, i'll see this case.

The root cause is JBCOMMON-25 which is now fixed.
