SDK tests on Java 25 are wery slow, other tests slow too

Go to https://download.eclipse.org/eclipse/downloads/drops4/I20260302-1800/

Note the test times and one "pending" test

Go to the pending test via https://ci.eclipse.org/releng/job/AutomatedTests/job/ep440I-unit-linux-x86_64-java25/

Note all recent test executions timed out or failed, most had timeout of 8 hours

Go to the last one https://ci.eclipse.org/releng/job/AutomatedTests/job/ep440I-unit-linux-x86_64-java25/6/

Check console log

Something is wrong with this machine or Jenkins.

Please check.

I've also noticed other tests are became slower in different other SDK related Jenkins builds.

Most recent example https://ci.eclipse.org/platform/job/eclipse.platform/job/PR-2545/1/stages/

timed out after one hour.
