limitation on hbj control in jsp ?

Has anyone experienced this wierd situation before.

I have a few hbj controls on my java iview. I am implementing a purchase order transaction (ME23N) as a java iview. Surely there are going to be a lot of hbj controls. Now I have reached a stage where it seems I cannot add any more. I get this error message. I have no idea why this is happening.

Error Message :

Caused by: java.lang.VerifyError: (class: pagelet/_sapportalsjsp_Form, method: doContent signature: (Lcom/sapportals/portal/prt/component/IPortalComponentRequest;Lcom/sapportals/portal/prt/component/IPortalComponentResponse;)V) Illegal target of jump or branch

Thanks for your help in advance
