RFR: 8357561: BootstrapLoggerTest does not work on Ubuntu 24 with LANG de_DE.UTF-8

[Matthias Baesken]

On a 'german'  Ubuntu 24 (LANG="de_DE.UTF-8") the jtreg test
java/lang/System/LoggerFinder/internal/BootstrapLogger/BootstrapLoggerTest fails with


FEIN: hi now!
java.lang.RuntimeException: System.err does not contain: FINE: hi now!
at BootstrapLoggerTest.main(BootstrapLoggerTest.java:231)
at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104)
at java.base/java.lang.reflect.Method.invoke(Method.java:565)
at com.sun.javatest.regtest.agent.MainWrapper$MainTask.run(MainWrapper.java:138)
at java.base/java.lang.Thread.run(Thread.java:1447)


The test (and some others in :tier1 as well) do not work with non en/US LANG, so they need an adjustment.
