I'm now trying to use it from NetBeans. Build & run work fine, but in the editor I have a lot of errors - even though the build works just fine. At the top of the file I get an error that java.lang could not be loaded - so I suppose the remaining errors stem from that one.
All imports seem to work fine, though. Anyone else experiencing this issue too? It makes it rather impractical to work with as the editor is full of errors.
