Jpy

* Publish artifacts to [PyPi](https://pypi.org/project/jpy/). Source tarball and binary wheels for Python 3.6 - 3.10 for Linux, Mac, and Windows (x86_64).
* Publish release to Maven Central with group id `org.jpyconsortium` and artifact id `jpy`. Java-8 compatible jars.
* Many more changes.

* Add the ability to pass properties and options to write_config_files. These values get passed
to the jvm when it is initialized.
[180](https://github.com/bcdev/jpy/pull/180#issue-513362903) Contribution by davidlehrian.
* Make jpy work with Anaconda by setting environment variable
`PYTHONHOME` from Java
[143](https://github.com/bcdev/jpy/issues/143). Contribution by Dr-Irv.
* Fixed: Constants are not properly passed from Java to Python when using interfaces
[140](https://github.com/bcdev/jpy/issues/140). Contribution by Dr-Irv.
* Fixed: Cannot iterate through a dict in Python 3.x
[136](https://github.com/bcdev/jpy/issues/136). Contribution by Dr-Irv.
* Automatically build 64-bit Python wheels for all Python versions from 3.4 to
3.8 on Linux, Windows, and Mac (fixes
[174](https://github.com/bcdev/jpy/issues/174)).

This version includes a number of contributions from supportive GitHub users. Thanks to all of you!

Fixes

* Corrected Java reference count of complex PyObject passed back and forth to methods (issue 120). Fix by sbarnoud.
* Fixed problem where default methods on Java 8 Interfaces were not found (issue 102). Fix by Charles P. Wright.
* Fixed error caused by missing `sys.argv` in Python when called from Java (issue 81). Fix by Dave Voutila.
* Fixed problem where calling jpy.get_type() too many times causes a memory access error (issue 74). Fix by Dave Voutila.
* Fixed a corruption when retrieving long values (72). Fix by chipkent.
* Fixed fatal error when stopping python session (issue 70, 77). Fix by Dave Voutila.
* Explicit null checks for avoiding JVM crash (issue 126). Fix by Geomatys.

Improvements

* Can now use pip to install Python `jpy` package directly from GitHub (83).
This works for Linux and OS X where C compilers are available by default
and should work on Windows with Visual Studio 15 installed.
Contribution by Dave Voutila.
* Java `PyObject` is now serializable. Contribution by Mario Briggs.
* Improved Varargs method matching. You may pass in either an array (as in the
past) or individual Python arguments, the match for a varargs method call is
the minimum match for each of the arguments. Zero length arrays (i.e. no
arguments) are also permitted with a match value of 10.
* `jpy.type_translations` dictionary for callbacks when instantiating Python objects.
* `jpy.VerboseExceptions` enables full Java stack traces.
* More Python exceptions are translated to the corresponding Java type.
* Globals and locals are converted when executing code with PyLib, to allow variables to be
used across statement invocation; and interrogated from Java.
* PyObject wrappers for dictionary, list, and introspection functions to tell
you whether or not you can convert the object.
* Support for isAssignable checks when dealing with Python Strings and primitives, to allow
matches for argument types such as `java.lang.Comparable` or `java.lang.Number`.

Fixes

* Java interface types don't include methods of extended interfaces (issue 64)
* Loading of jpy DLL fails for user-specific Python installations on Windows (issue 58)
* Java interface types didn't expose java.lang.Object methods (issue 57)
* Java 1-arg static method was confused with a zero-arg non-static method (issue 54)
* Python interpreter crash occurred when executing del statement on Java arrays (issue 52)
* Python extensions loaded from Java couldn't see Python symbols (Linux) (issue 38)

Improvements

* It is now possible to use jpy Java API to work with multiple Python installations (issue 35).
A tool called 'jpyutil.py' can be used to write configuration files that determine the required shared libraries
for a given Python versions.
A new Java system property 'jpy.config' is used to point to a desired configuration file.
* Simplified jpy installation (issue 15):
- removed need to add JVM path to PATH (Windows) / LD_LIBRARY_PATH (Unix) environment variable
- removed need to compile Java module using Maven
- removed need to specify JDK_HOME environment variable, if JAVA_HOME already points to a JDK
* Added 'jclass' attribute to Python type that wraps a Java class (issue 63) .
* Java API extensions
- new `jpy.org.PyObject.executeCode()` methods
- new `jpy.org.PyModule.getBuiltins()` method
- new `jpy.org.PyModule.getMain()` method
- new `jpy.org.PyModule.extendSysPath()` method
* Java API configuration changes:
- System property `jpy.jpyLib`:
- System property `jpy.jdlLib`:
- System property `jpy.pythonLib`:
- System property `jpy.config`:
- Loaded from
- File `./jpyconfig.properties`
- Resource `/jpyconfig.properties`
- File `${jpy.config}`
* Python API configuration changes:
- Loaded from
- File `./jpyconfig.py`
- Resource `${jpy-module}/jpyconfig.py`
- Attribute java_home
- Attribute jvm_dll
* Python API extensions
- new `jpyutil` module
- `jpyutil.init_jvm(...)`
- `jpyutil.preload_jvm_lib(...)`
- new `jpyutil` tool
- usage: `jpyutil.py [-h] [--out OUT] [--java_home JAVA_HOME] [--jvm_dll JVM_DLL]`
* Added basic support for Java Scripting Engine API (issue 53)

Other changes

* Switched to Apache 2.0 license from version 0.8 and later (issue 60)

* Fixed bad pointer in C-code which caused unpredictable crashes (issue 43)

* Fixed a problem where jpy crashes with unicode arguments (issue 42)
* Fixed segmentation fault occurring occasionally during installation of jpy (issue 40)
* Improved Java exception messages on Python errors (issue 39)
