Jdk-8182746 Java 8u121 On Linux Intermittently Returns Null For Mac카테고리 없음 2020. 4. 10. 14:44
After updating from Java 8u101 to Java 8u121, Java application running with Tomcat shows intermittent failure getting MAC address. The application connects to other apps on other systems by using MAC address to resolve IP address for connection. Intermittently, a thread will show a null MAC address is returned and Tomcat log reports: CRITICAL ERROR: ip address is not assigned to a valid ethernet interface. The problem does not occur with single CPU/thread. It occurs with multiple CPUs/threads, under load.

The problem is not seen on Windows or MacOSX. The problem is seen only on Linux systems using 8u121 or 8u131. The problem does not occur when Java 8u101 is used on the same systems with the same application version. Java 8u121 reproduces the issue at a lesser rate than 8u131. The problem takes about 50TPS on 8u121, but needs only a couple threads on 8u131 to reproduce it.

軟體資訊 檔案版本 Java JDK 8 Update 112 (32-bit) 檔案名稱 jdk-8u112-windows-i586.exe 檔案大小 188.99 MB 系統 Windows Vista / Windows 7 / Windows 8 / Windows 10 軟體類型 免費軟體 作者 官網 更新日期 更新日誌 What's new in this version: CHANGES: security-libs/java.security: - SunPKCS11 Provider no longer offering SecureRandom by default - SecureRandom.PKCS11 from the SunPKCS11 Provider is disabled by default on Solaris because the native PKCS11 implementation has poor performance and is not recommended. If your application requires SecureRandom.PKCS11, you can re-enable it by removing 'SecureRandom' from the disabledMechanisms list in conf/security/sunpkcs11-solaris.cfg - Performance improvements have also been made in the java.security.SecureRandom class. Improvements in the JDK implementation have allowed for synchronization to be removed from the java.security.SecureRandom.nextBytes(byte bytes) method.
