jdk1.7使用JVM的UseSplitVerifier参数导致报NoClassDefFoundError: oracle/security/pki/OraclePKIProvider

 

 

场景

1、应用使用1.7的jdk

2、使用字节码工具修改字节码

 

问题

使用字节码工具修改字节码的时候，为了禁用字节码验证，使用-XX:-UseSplitVerifier的JVM参数禁用字节码验证,出现如下报错：

原因

使用jdk1.7的-XX:-UseSplitVerifier参数禁用字节码验证，

且从oracle驱动JDBC版本1.1.0.2.0及更高版本 ，应用程序启动的是会报NoClassDefFoundError：oracle/security/pki/OraclePKIProvider异常。

 

临时解决

1、更换JDK，避免使用-XX:-UseSplitVerifier的JVM参数禁用字节码验证

2、更换oracle驱动
