Memory management 添加自定义采样器后Jmeter在启动时崩溃

我为Jmeter编写了一个自定义采样器，但在将其添加到Jmeters lib/ext文件夹后，它在启动时崩溃。出现以下错误：

java.lang.OutOfMemoryError: PermGen space
Dumping heap to java_pid1448.hprof ...
Heap dump file created [23456544 bytes in 0.490 secs]
Uncaught Exception java.lang.OutOfMemoryError: PermGen space. See log file for details.
