cannot find newInstance() symbol #32
Description
I try to compile my NC_writer class with
Class<?> Netcdf_writer = InMemoryJavaCompiler.newInstance().compile("meteoread.NC_writer", sourceCode.toString());
but it is not possible because newInstance() symbol cannot be found. I can use just
Class<?> Netcdf_writer = InMemoryJavaCompiler.compile("meteoread.NC_writer", sourceCode.toString());
It works in NetBeans IDE but after I built the program and I run the .jar file I get NulPointerException error. How should I fix this problem? I use InMemoryJavaCompiler-1.2

I have downloaded the InMemoryJavaCompiler-1.3.0. I could use:
Class<?> Netcdf_writer = InMemoryJavaCompiler.newInstance().compile("meteoread.NC_writer", sourceCode.toString()); DataNcSource instance = (DataNcSource) Netcdf_writer.newInstance(); instance.getDataNc();but after I run my .jar program I got the NulPointerException as well:
How should I fix this error?
