The latest early access version of Java 24, i.e, 24+26 fails to start when -Djava.security.manager=allow is specified. I.e., eclipse quietly fails to start; via the console we see why/how it fails to start:
$eclipse/eclipse.exe -consoleLog 2>&1 | tee log
CompileCommand: exclude org/eclipse/jdt/internal/core/dom/rewrite/ASTRewriteAnalyzer.getExtendedRange bool exclude = true
WARNING: Using incubator modules: jdk.incubator.vector
Error occurred during initialization of VM
java.lang.Error: A command line option has attempted to allow or enable the Security Manager. Enabling a Security Manager is not supported.
at java.lang.System.initPhase3(java.base@24-beta/System.java:1948)
That option is specified in the eclipse.ini and is used in quite a few places (in the Platform SDK setup):
Even if we were to remove this option from the product, existing installations would retain the option in the eclipse.ini when updating.
Starting with -Djava.security.manager=disallow allows the IDE to start, though it's not so pretty!

For further testing, I provisioned the Oomph Platform SDK setup using Java 24 and specifying -Djava.security.manager=disallow. That mostly works fine:
I think we shouldn't be logging error from Ant when failing to set the security manager is an expected thing.
I think in preparation for upcoming releases of Java we should use -Djava.security.manager=disallow and fix any problems related to that.
Note
sun.misc.Unsafe will become a bigger problem eventually--enable-native-access=ALL-UNNAMED will eventually be needed- WindowsDefenderConfigurator doesn't work
