JDK 6 may work, but isn't supported, since it is no longer supported by it's creator and developers of Javapoet.
Passing invalid expressions as annotation parameters may not be correctly detected during validation step and results in runtime exception during compilation with Javac.

Example:
```
// will fail to compile with ugly message, asking you to send a bug report :(
@AIDL(SomeNonExistingType.DESCRIPTOR)
```
This is due to limitations of Javac, which converts erroneous "types" to strings before passing them to AnnotationValueVisitor. This also happens with other annotation processors, such as ButterKnife.
Generated implementations of interfaces, containing intersection types, may fail to compile with source versions before Java 8.
```
// this will fail to compile with JDK 7
<T extends Parcelable & Runnable> void methodWithIntersectionArgument(T param);
```
This is because implementing those requires support for either advanced type inference or casts to intersection, both of which didn't exist until Java 8.
Some of generated files may contain redundant casts. This is due to limitation of Java compilers, which sometimes fail to correctly tell annotation processors whether a cast is needed (this tends to happen when generics are involved).
Nonsential intersection types like Boolean & Runnable aren't detected. I believe, that those should be handled by the compiler.
