commit 19d2ec6539f789dfbe38612e5e7807cac9fe0819
Author: Stephan Bergmann <sbergman at redhat.com>

    Don't pass empty option to JNI_CreateJavaVM
    
    sUserClassPath may be empty (instead of containing "-Djava.class.path=...")
    here, which older versions of Java have apparently silently ignored.  But
    Java 10 now fails with JNI_EINVAL (-6).  (Happens e.g. during
    CppunitTest_dbaccess_hsqldb_test.)
