Help needed -- Exception thrown when migrated from v3.3 to v4.3

Hi

 

We migrated from v3.3 to v4.3 but encountered problems when using proxy.vaultQueryByCriteria in the following code. This code was running fine under v3.3.

 

 

The error message is shown as below:

 

 

 

The Class GrantsState has constructor with @ConstructorForDeserialization as shown below and each property has a getter. Plus this code is running fine under v3.3.

 

 

 

Any help is highly appreciated!

Many thanks!

It looks like your javac command line has lost its -parameters flag along the migration. Without this flag the names of method parameters won't be available for reflection, which can be seen in the error message. We should detect this case and provide a better error explaining how to fix it. Does adding that flag (back) work?

Hi Mike,

 

Thank you very much for your insights! Yes, -parameter flag made it through!

 

Cheers!

Avery
