RESTful service on overloading method in WebLogic

Question

I am using WebLogic 12.1.2. (It seems to be a WebLogic issue because the same code works fine under JBoss)

I have an EJB with overloading methods. If I assign both method with same RESTful path, the deployment on WebLogic will appear to be success but fail when I access the EJB method with this message:

Root cause of ServletException.
com.sun.jersey.spi.inject.Errors$ErrorMessagesException
    at com.sun.jersey.spi.inject.Errors.processErrorMessages(Errors.java:170)
    at com.sun.jersey.spi.inject.Errors.postProcess(Errors.java:136)
    at com.sun.jersey.spi.inject.Errors.processWithErrors(Errors.java:199)
    at com.sun.jersey.server.impl.application.WebApplicationImpl.initiate(WebApplicationImpl.java:770)
    at com.sun.jersey.server.impl.application.WebApplicationImpl.initiate(WebApplicationImpl.java:765)

Here is my EJB code:

  @Stateless
  @LocalBean
  @TransactionManagement(TransactionManagementType.BEAN)
  @Path("/License")
  public class License implements LicenseRemote, LicenseLocal {

  public License() {
  }

  @POST
  @Path("/registerTerminal")
  @Produces("application/json")
  public ResultRecord registerTerminal(
        @QueryParam("machineName") String machineName,
        @QueryParam("computerName") String computerName,
        @QueryParam("terminalId") String terminalId) {

    ..............
    ...............
    ...............
  }

  @POST
  @Path("/registerTerminal")
  @Produces("application/json")
  public TerminalInfo registerTerminal(
        @QueryParam("terminalId") String terminalId) {

    ..............
    ...............
    ...............

  }

If I change one of the Path annotation to different value, then everything works fine.

Thanks in advance for any help!
