The three sightings of this failure mode (so far) are on
linux-aarch64 or linux-x64 and have the following JVM args:

The root cause is a difference between the Java implementation of the toBytes() method and the intrinsic. The test will need to be relaxed to accept the error message produced by the intrinsic. It seems too picky to require the intrinsic to produce particular error messages.

In jdk-23+2-54, there are total of 20 runs of java/lang/String/CompactString/MaxSizeUTF16String.java and 17 of those pass on all the usual platforms so just these three fail. [~rriggs] - the following bug fix is included in jdk-23+2-54: JDK-8321180 Condition for non-latin1 string size too large exception is off by one and that bug report mentions the exception output that we're seeing in these failures: java.lang.RuntimeException: Wrong exception message: Requested array size exceeds VM limit so I'm wondering if that fix caused this test to fail. Correction: JDK-8321180 introduced java/lang/String/CompactString/MaxSizeUTF16String.java as a new test so I'm lowering the priority from a P2 (a regression starts here) to a P3 (new test is failing noisily).
