This commit is the culprit:
http://hg.openjdk.java.net/jdk-updates/jdk11u/rev/21710e014d7f

It makes sense since it is related to System.loadLibrary().

Because Scilab loads Java from C++ code I guess moving usr_paths ans
sys_paths initialization out of System.loadLibrary might have some
consequences.

Applying the attached patch to openjdk-11 solves the problem. Not sure
this is the right thing to do, but it keeps the deadlock fix brought by
the jdk changeset and allows for sys_paths and usr_paths initialization
in System.loadLibrary() when needed.

@doko, please consider adding this patch to the openjdk-11 source
package until a proper fix is found for Scilab.

Thanks,

_g.
