This could be caused by the fix for JDK-8209093
Comments
This problem was introduced with the changes made to the test to remove the AARCH64 platform check. I had assumed that the only unsupported platform was the AARCH64 port that I removed. I missed the fact that Windows does not support this feature. 235 private static boolean isAlwaysSupportedPlatform() { 236 // Note: To date Aarch64 is the only platform that we don't statically 237 // know if it supports the reserved stack area. This is because the 238 // open Aarch64 port supports it and the Oracle arm64 port does not. 239 return Platform.isAix() || 240 (Platform.isLinux() && 241 (Platform.isPPC() || Platform.isS390x() || Platform.isX64() || 242 Platform.isX86())) || 243 Platform.isOSX() || 244 Platform.isSolaris(); 245 } 246 247 private static boolean isNeverSupportedPlatform() { 248 return !isAlwaysSupportedPlatform() && !Platform.isAArch64(); 249 }
