java.lang.LinkageError caused by IoslatingClassLoader.java

[Fourseas54]

There is a project named GrowingBugRepository(https://github.com/liuhuigmail/GrowingBugRepository),which can be considered as same as Defects4j. And there is a newly mined bug which is mined from apache/commons-dbcp project. When I run gzoltar on this bug, there is an error:
java.lang.LinkageError: loader constraint violation: loader (instance of com/gzoltar/internal/core/util/IsolatingClassLoader) previously initiated loading for a different type with name "javax/management/MBeanServer"
I simply thought that was due to dependency violation. But I didn't find javax.management after running "mvn dependency:tree" on root directory of gzoltar.
Then I modified com/gzoltar/internal/core/util/IsolatingClassLoader and simply added an if statement:
if (name.contains(".management")){
return super.loadClass(name,resolve);
}
And gzoltar can running perfectly on that apache/commons-dbcp project.
But there may be more elegant way to fix it.
I hope you can help me solve this problom, thank you!
