由于错误而无法启动Jmeter 3.1类文件中的未知常量标记204 javax / swing / RepaintManager errorlevel = 1

Question

尝试启动Jmeter 3.1时出现错误

An error occurred: Unknown constant tag 204 in class file javax/swing  /RepaintManager

错误级别= 1

我在本地系统中运行了100个用户测试（RAM为16GB）并在执行之后停止了测试，此后面临此问题。请建议。

Answer 1

您的JVM很可能已损坏，请参阅：

• How to fix: Unknown constant tag 32 in class file com/sun/org/apache/xerces/internal/impl/xs/XMLSchemaValidator

重新安装JDK 7或8（建议）。

我还建议你升级到最后的JMeter 3.2

感谢@UBIK LOAD PACK寻求帮助和指导。重启系统后（2次，一次系统通过显示错误代码自动重启：内存管理问题），能够成功启动Jmeter 3.1。
