may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

Support functions for Android's class libraries
These are VM-agnostic native functions that implement methods for system
class libraries. All code here:
- MUST not be associated with an android.* class (that code lives in
frameworks/base/).
- SHOULD be written in C rather than C++ where possible.
Some helper functions are defined in include/nativehelper/JNIHelp.h.

/**
* A cache to avoid calling FindClass at runtime.
*
* Class lookup is relatively expensive (2.5us on passion-eng at the time of writing), so we do
* all such lookups eagerly at startup. This means that code that never uses, say,
* java.util.zip.Deflater still has to pay for the lookup, but it means that on a device the cost
* is definitely paid during boot and amortized. A central cache also removes the temptation to
* dynamically call FindClass rather than add a small cache to each file that needs one. Another
* cost is that each class cached here requires a global reference, though in practice we save
* enough by not having a global reference for each file that uses a class such as java.lang.String
* which is used in several files.
*
* FindClass is still called in a couple of situations: when throwing exceptions, and in some of
* the serialization code. The former is clearly not a performance case, and we're currently
* assuming that neither is the latter.
*
* TODO: similar arguments hold for field and method IDs; we should cache them centrally too.
