[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - thin driver ojdbc14.jar, Java 6 (1.6) and -Xss

[mclu]

Hi out there!

We are using Jboss 4.x with Oracle 9 and 10.

Because in the Java 5 there are some Bugs/Issues with Threads we are forced to upgrade to Java 6. We are using plain J2EE with EJB 2.0 and mostly 1.1

With Java 6 and MSSQL all works but not with Oracle. We we found the Error...
It has to Do with the VM Parameter -Xss (Setting Stack Size)
At JBoss we are using the Thin Driver and the newest ojdbc14.jar

Configutation DS:
<local-tx-datasource>
    <jndi-name>AeosDS</jndi-name>
    <connection-url>jdbc:oracle:thin:@NVC0534:1521:test</connection-url>
    <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
    <min-pool-size>0</min-pool-size>
    <max-pool-size>50</max-pool-size>
    <security-domain>MyDatabaseRealm</security-domain>
    
      <type-mapping>Oracle9i</type-mapping>
    
  </local-tx-datasource>

When we now start the Server without the -Xss setting all is OK.
When I start up the Server with -Xss64k I get a NoClassDefFoundError ???
Stacktrace:

Why the Driver change his behaviour dependend on the Xss setting?
Is there a Bug on Jboss side?
I Also posted this in the Oracle Tech Channel.

With an older Version like the classes12.jar it works!!
