for core:
[INFO] com.github.jnr:jnr-constants .......................... 0.8.4 -> 0.8.5
[INFO] com.github.jnr:jnr-ffi ................................ 1.0.5 -> 1.0.7
[INFO] org.yaml:snakeyaml ...................................... 1.12 -> 1.13

for the tests:
[INFO] org.apache.ant:ant .................................... 1.8.4 -> 1.9.2
[INFO] rubygems:minitest ..................................... 5.0.6 -> 5.0.7

for jopenssl
[INFO] org.bouncycastle:bcpkix-jdk15on ......................... 1.47 -> 1.49
[INFO] org.bouncycastle:bcprov-jdk15on ......................... 1.47 -> 1.49

bouncy castle will produce compilation errors and there are no tests for that particular pbk... so better keep the version

what about ant ?

the rest looks just OK to go - or is it too close to the release of 1.7.5 ?
