Can't install java agent on jboss 7.1.1

CommunityUser — Fri, 04 Oct 2013 18:14:24 GMT

My application deploys well as normal, but as soon as I install the java agent I get the following error:

Caused by: java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "org.postgresql.xa.PGXAConnection.getXAResource()Ljavax/transaction/xa/XAResource;" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, org/postgresql/xa/PGXAConnection, and the class loader (instance of <bootloader>) for interface javax/sql/XAConnection have different Class objects for the type on/xa/XAResource; used in the signature

Any ideas?

Hey,

We are getting the same issue with mysql drive and jboss 7.1.1

Caused by: java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "com.mysql.jdbc.jdbc2.optional.MysqlXAConnection.getXAResource()Ljavax/transaction/xa/XAResource;" the class loader (instance of org/jboss/modules/ModuleClassLoader) of the current class, com/mysql/jdbc/jdbc2/optional/MysqlXAConnection, and the class loader (instance of <bootloader>) for interface javax/sql/XAConnection have different Class objects for the type javax/transaction/xa/XAResource; used in the signature

Only happens for xa-datasources,

Hi,

Can you please provide the startup scripts used to add -javaagent, if restarting jboss server does not help after adding the following jvm arg:

-Dappdynamics.bciengine.class.lookahead=!*

Also can you confirm whether you have added -javaagent arg in both -Xbootclasspath and java_opts, if this is the case, please remvoe javaagent.jar entry -Xbootclasspath args.

Thanks,

Arun
