Issue Description
JDK-8341779

`TypeMirror` Changed to Provide Annotations for Types Loaded from Bytecode


The implementation of TypeMirror now provides access to annotations for types loaded from bytecode. Previously type annotations were not associated with types loaded from bytecode.

Annotation processors can access type annotations for elements using AnnotationMirror#getAnnotationMirrors, and the annotations will be included in the output of AnnotationMirror#toString.

Any programs that relied on annotations being omitted for elements loaded from the classpath should be updated to handle type annotations.

Issue Description
JDK-7036144

`GZIPInputStream` Will No Longer Use `InputStream.available()` to Check for the Presence of Concatenated GZIP Stream


The GZipInputStream read methods have been modified to remove the usage of InputStream::available() when determining if the stream contains a concatenated GZIP stream. These methods will now read any additional data in the underlying InputStream and check for the presence of a GZIP stream header.
