Unsafe call to 'Class.newInstance()'

Reports calls to java.lang.Class.newInstance().

This method propagates exceptions thrown by the no-arguments constructor, including checked exceptions. Usages of this method effectively bypass the compile-time exception checking that would otherwise be performed by the compiler.

A quick-fix is suggested to replace the call with a call to the java.lang.reflect.Constructor.newInstance() method, which avoids this problem by wrapping any exception thrown by the constructor in a (checked) java.lang.reflect.InvocationTargetException.



After the quick-fix is applied:
