Adapt gc/arguments tests for the JDK 17 kernel differences in flag printing format, ergonomics derivation logic, and option deprecation/inheritance: 1. TestAggressiveHeap.java: Relax regex to accept both `=` and `:=` for PrintFlagsFinal output, matching the JDK 17 format change for command-line-originating values. 2. TestG1ConcRefinementThreads.java: Handle JDK 17 preserving explicit G1ConcRefinementThreads=0 instead of replacing it with the ergonomic ParallelGCThreads value. 3. TestG1HeapRegionSize.java: Lower the tested G1HeapRegionSize cap from 64m to 32m to avoid JVM initialization failure on the JDK 17 kernel. 4. TestHeapFreeRatio.java: Use generalized regex to match the changed illegal HeapFreeRatio error message format in JDK 17. 5. TestInitialTenuringThreshold.java: Accept MaxTenuringThreshold=16 combined with InitialTenuringThreshold=8 as a valid startup configuration on JDK 17. 6. TestUnrecognizedVMOptionsHandling.java: Adapt expectations for CompoundVM legacy option alias compatibility (PrintGc, MaxiumHeapSize); these no longer fail with "Did you mean..." suggestions. 7. TestUseCompressedOopsErgoTools.java: Use regex to extract the heap size value from stdout, avoiding NumberFormatException caused by JDK 17 WhiteBox registration warnings polluting the output.
