----------------------------
Description:
org.codehaus.groovy.runtime.callsite.CallSiteClassLoader#[loadClass|https://github.com/apache/groovy/blob/GROOVY_4_0_27/src/main/java/org/codehaus/groovy/runtime/callsite/CallSiteClassLoader.java#L47](String,boolean)
is using `synchronized` keyword at method level，
this can be improved by using className level lock,
such as JDK's
java.lang.ClassLoader#[loadClass|https://github.com/openjdk/jdk/blob/jdk-11%2B28/src/java.base/share/classes/java/lang/ClassLoader.java#L565C24-L565C33](String,boolean)
```java
protected Class<?> loadClass(String name, boolean resolve)
throws ClassNotFoundException {
synchronized (getClassLoadingLock(name)) {
// ...
}
}
```
