EDIT: I have managed to track the code that's on the method being renamed, that is causing the exception (I've been trying different combinations until I found the one.)

The method being processed has the code 	

{{new FileRemoveLog(this, UserView.getCurrentUser(), file.getFilename(), file.getDisplayName() != null ? file.getDisplayName() : file.getFilename(), BundleUtil.getLocalizedNamedFroClass(file.getClass()));}}
In which the FileRemoveLog constructors signature is {{public FileRemoveLog(WorkflowProcess process, User person, String... argumentsDescription)}}

However, changing the code to the following will no longer raise the exception.

{{	new FileRemoveLog(this, UserView.getCurrentUser(), file.getFilename(),
	/*
	 * file.getDisplayName() != null ? file.getDisplayName() :
	 * file.getFilename()
	 */
	BundleUtil.getLocalizedNamedFroClass(file.getClass()));}}

      was (Author: jpcarvalho):
    The actual test case isn't very relevant to this problem, we've tried with several versions of the injected method, like the original body, just printing something to System.out, empty body, all of them raise that exception. 

The injection code has been in production for quite a while, and simply renames the method, and wrapping a call to that method...
