Fix status: documented_behavior Misleading approaches: - Reinstalling the JDK — the offending flag is in configuration. Limitations: - Source-derived; not reproduced. - MaxPermSize is used as a representative example; the exact JDK where a given flag expired depends on the flag (table entries are removed once expired). Other error fragments: - Error: Could not create the Java Virtual Machine. - Error: A fatal exception has occurred. Program will exit. - Ignoring option --illegal-access=permit; support was removed in 17.0 Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/openjdk/jdk/1587398892ce98284c9c994b14696a96cd43e1ed/src/hotspot/share/runtime/arguments.cpp (official_docs, unknown, documented_behavior): special_jvm_flags lifecycle: at obsolete_in the flag is accepted with a warning and ignored ('Ignoring option %s; support was removed in %s'); at expired_in the JVM refuses it; unknown flags print "Unrecognized VM option '%s'" with optional "Did you mean ..."; --illegal-access= is ignored with a removed-in-17 warning. - https://raw.githubusercontent.com/openjdk/jdk/1587398892ce98284c9c994b14696a96cd43e1ed/src/java.base/share/native/libjli/emessages.h (official_docs, unknown, documented_behavior): Launcher JVM_ERROR1: 'Error: Could not create the Java Virtual Machine.' followed by 'Error: A fatal exception has occurred.
