Richard N. Hillegas commented on DERBY-7126: -------------------------------------------- My naive attempt to workaround the new hurdle introduced by JDK 18 was to programatically set the "java.security.manager" property just before calling System.setSecurityManager()--as we do with the other properties related to the SecurityManager. Unfortunately, this does not allow the SecurityManager to be installed. However, if I set that property on the boot command line, then the SecurityManager can be installed. I have attached a simple program (DERBY_7126_B), which demonstrates this behavior. Here is the output from running the program against JDK 18 WITHOUT setting "java.security.manager": {noformat} mainline (18) > java DERBY_7126_B Exception in thread "main" java.lang.UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release at java.base/java.lang.System.setSecurityManager(System.java:411) at DERBY_7126_B.main(DERBY_7126_B.java:34) {noformat} And here is the output from running the program against JDK 18 and setting "java.security.manager" on the boot command line: {noformat} mainline (18) > java -Djava.security.manager=allow DERBY_7126_B WARNING: A terminally deprecated method in java.lang.System has been called WARNING: System::setSecurityManager has been called by DERBY_7126_B (file:/Users/rhillegas/src/) WARNING: Please consider reporting this to the maintainers of DERBY_7126_B WARNING: System::setSecurityManager will be removed in a future release {noformat} Looks like another trip to the Open JDK security mailing list is in order. > Make it possible to build and test Derby cleanly with OpenJDK 18 > ---------------------------------------------------------------- > > Key: DERBY-7126 > URL: https://issues.apache.org/jira/browse/DERBY-7126 > Project: Derby > Issue Type: Task > Components: Build tools > Affects Versions: 10.16.0.0 > Reporter: Richard N.
