Set --sun-misc-unsafe-memory-access=warn (JEP 498)

• JDK 26 will change the default from warn it to deny and throw on Unsafe mem access method usage, this sets it back
• gives us more time to update the dependencies (till JDK 27)

note: as of 26b23, this isn't implemented yet

set -J-Dguice_custom_class_loading=CHILD

• this will lead guice to code paths which don't use Unsafe for class definition
  (e.g it won't use com.google.inject.internal.aop.HiddenClassDefiner)
• maven 4 uses the same trick (Set Guice class loading to CHILD - avoid using terminally deprecated methods maven#11002)

wondering if we should set it in
https://github.com/apache/netbeans/blob/master/nbbuild/jms-config/base.flags instead,

or append to

netbeans/nbbuild/templates/projectized.xml

Line 333 in b535ff5

<property name="test.run.args" value="-ea -Xms1200m -Xmx1200m -XX:+UseParallelGC ${metabuild.jms-flags.jvm} ${test.jms.flags} -XX:+IgnoreUnrecognizedVMOptions"/>

.

Since that way tests would pick it up too. They might start failing at some point.

I have no idea what too choose. JDK 26 will "freeze" change begining december ?

not sure. JEP states "deny will be the default value in phase 3 (JDK 26 or later)", maybe it won't even be changed in JDK 26 - I don't know.

we could keep it as is and only add it to the .conf. When the tests start failing we add it either globally or only for those modules which failed at that time.

I it's helps go for the more convenient
