Pmemkv Java Versions Save

Improvements:

• add ReadIterator experimental API - it allows iterating through records and read (currently only entire) value
• add new Builder methods to read config params from JSON objects

Requirement notice:

• since this release, pmemkv is required in version at least 1.4

Improvements:

• improve performance over 2 times by caching direct buffers and optimizing JNI calls (of callbacks)
• add new Builder methods to adjust direct buffers' sizes
• use pmemkv C++ API (instead of C) in JNI layer

Minor changes:

• set up configurable test path
• update documentation

Other:

• rethrow user exception in get_above/all/below/between instead of StoppedByCallbackException
• adjust versioning scheme to match Semantic Versioning (always provide patch version)

Improvements:

• simplify compilation
• generated JAR files include dependencies
• every example is compiled to runnable JAR
• remove oleaster-matcher dependency
• change Maven modules paths
• disable javadoc generation for examples
• add throws clauses to Database methods

Bug fixes:

• fix occasional crash in finalize method
• add error handling for count* methods
• remove unnecessary dependency to libpmemkv_json_config

This is the first pmemkv-java release which is fully compatible with pmmekv 1.0 and guarantees backward compatibility.

Major changes:

• API redesign (support for an arbitrary type with converter to ByteBuffer)
• config API redesign with builder pattern
• extended exception list
• extended documentation
• build system refactor to start using mvn only
• project merge with pmemkv-jni

This release adjusts pmemkv-java to work with pmemkv 1.0

This is the first official release of pmemkv-java project.

It provides Java bindings to libpmemkv 0.8 with simplified API and not functionally equal to its native C/C++ counterpart.
