[rap-dev] Rap 2.3 cannot registerServiceHandler from Actviator

[drpadawan <drpadawan@xxxxx>]

Hi Everyone,

I have a plug-in with an activator where I want to register my service handlers. After moving to RAP 2.3 from RAP 1.4 I'm getting InvalidStateException in RWT.getApplicationContext.

What is the best place to register my Service handlers?

Thanks

Root exception:
java.lang.IllegalStateException: Invalid thread access
