javah is no longer present with openJDK11
Fedora recently switched to OpenJDK11 and it appears that that version no longer includes the javah command:
as a result, the java bindings cannot be built. According to the fedora change page, using java -h should be equivalent, but the syntax is different and I didn't figure out a way to build with java -h. This is mostly my ignorance, I guess, because I have literally never used Java in my life.
Does lasso upstream plan to support OpenJDK 11?
