解決方法：
修改tools.sh內的JAVA配置,添加jre/lib/ext目錄

gedit tools.sh

修改：

將:
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"
修改成:
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext:/java/jdk1.8.0_241/jre/lib/ext"

注意:jdk11沒有jre目錄，需要手動下載
