[seth/nqzero]

2.0.0-20 is released

https://github.com/nqzero/kilim/

the artifact is available on maven central including several jdk-specific versions in org.db4j:kilim

  2.0.0-20

  2.0.0-20-jdk7

  2.0.0-20-jdk10

  2.0.0-20-jdk11

multiple versions are used instead of multiple classifiers to allow using the artifact as a plugin for ahead-of-time weaving (see the readme for an example). the jdk-specific differences are mostly minor. other than `-jdk7`, all are compiled against java 8. `-jdk10` includes a workaround (see the readme) for a lambda-validation bug in java 10.0.2 (expected to be fixed in the next oracle release on oct 16). `-jdk11` includes ASM's "experimental" support for java 11

all tests pass with all versions, for both AOT and runtime weaving, and there are demos of each one in `demos`
