java.lang.VerifyError: Expecting a stackmap frame

Question

Is there a way to load a custom HttpServlet to GAE? I uploaded a project that included an HttpServlet in the .server package and added it to the web.xml...

&         


        

Answer 1

I could solve this issue by setting Eclipse Mars / Project properties / Java compiler :

• Compiler compliance level to 1.7 (as I don't have 1.6 anymore)
• Generated .class files compatibility : 1.6
• Source compatibility : 1.6

as I didn't have 1.7 specific code :-)
