Issue with bean validation using hibernate-validator api and size validation.

Solution Verified - Updated -

Environment

  • Red Hat JBoss Fuse
    • 6.1.1

Issue

  • User is facing a problem with Bean validation.
  • User used the implementation suggested in https://access.redhat.com/solutions/734273
  • Everything works as expected but when a javax.validation.constraints.Size is not satisfied an exception is thrown:
Caused by: java.lang.ClassNotFoundException: com.sun.el.ExpressionFactoryImpl not found by xxx.yyy.zzz [295]

  • Constrains of type javax.validation.constraints.NotNull work without throwing errors.
  • It seems that the javax.el.ExpressionFactory factory is using bundle A classloader to instantiate the com.sun.el.ExpressionFactoryImpl
  • If User add Import-package: com.sun.el to the bundle then another exception is thrown:

Resolution

  • JIRA request has been raised, which can be tracked at https://issues.jboss.org/browse/ENTESB-3402.
  • There is a workaround where user can switch version of hibernate-validator bean to an earlier version i.e. 4.3.1.Final.
  • In pom.xml replace the existing dependency with following. Build the code with this dependency.
<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-validator</artifactId>
   <version>4.3.1.Final</version>
</dependency>
  • Also deploy this dependency to Fuse environment.
