Many methods do not use `IExecuteWithSignature`, but fallbacks into the `IExecute` method

[masesdevelopers]

In the last reflection, many methods do not use anymore IExecuteWithSignature, but fallbacks into the IExecute method reporting, as can be seen in the attached file (JNetReflector.txt), the following error:

Error: SignatureFromGenericString: signature not found for method getDip (Generic string: public boolean android.text.style.AbsoluteSizeSpan.getDip()) of class android.text.style.AbsoluteSizeSpan using public boolean android.text.style.AbsoluteSizeSpan.getDip() not found.

The code is able to work using the IExecute method, however an issue will be opened on JNet to check it.
