ClassUtils: Caching of annotated Fields is not thread safe

@hinerm @ctrueden Following example fails with error message: "Context already injected ..." (sorry for using SCIFIO to demonstrate a SciJava Bug): ``` public static void main(String[] args) { final SCIFIO...

The `CacheService` interface contains a bogus implementation of the method `get(String key, Callable valueLoader)`, which never actually invokes the `valueLoader`. Probably, the default implementation should invoke `valueLoader.call()` iff a call...

Some modules are dynamic during initialization, but once the `initialize()` stuff has been done, parameters are fixed. Other modules want to be dynamic during callbacks (i.e., changes to parameter values),...

Collection type outputs not handled correctly

1

The following script: ```groovy [1,0.5] ``` returns an `ArrayList` that is (correctly) handled by `DisplayPostprocessor`: https://github.com/scijava/scijava-common/blob/821f89fc53bd2f3ffe75c14cd35eb74d5b4e545e/src/main/java/org/scijava/display/DisplayPostprocessor.java#L149-L156 The recursively-called private `handleOutput` method however doesn't handle numerical outputs, resulting in the following...

Allow differentiating between lossy and lossless object conversion

2

Currently we can ask `ConvertService` whether a certain conversion is supported via: ``` convertService.supports(sourceObject, targetType) ``` It would be great to have some possibility to differentiate what degree of conversion...
