To refresh with Java 8 environment:

Following @sleske answer

System.setProperty("javax.net.debug","all");

worked for me out of the box.

Also was @weberjn suggestion of

strace -o strace.out -s 4096 -e trace=network -f java

but not useful if handling with SSL traffic as it dumps encoded stream.

All other code tricks did not work for me, but maybe not trying enough hard.
