Fix build for JDK 18 >= EA b21 (#1249)

Godin · web-flow · commit 024de66740f7 · 2021-11-17T18:30:50.000+01:00
Ant task `java` with parameter `fork="false"` calls `java.lang.System.setSecurityManager`, however tests should not call it, because as part of work on JEP 411 in JDK 17 it was marked as deprecated (see https://bugs.openjdk.java.net/browse/JDK-8264713) and in JDK 18 throws UnsupportedOperationException unless system property `java.security.manager` set to `allow` (see https://bugs.openjdk.java.net/browse/JDK-8270380).
