Kathey Marsden commented on DERBY-4287:
---------------------------------------
Thank you Knut, I think that must be the reason. If I try with ij and the
derby_tests.policy file with just the property part of the change. I can get an
error on creation of the FileOutputStream. With the full change the class file
is created properly.
This makes me wonder if in general, liberal permissions in derbyTesting.jar
might be masking security manager issues in the product.
> call to System.getProperty in BCClass.java is not wrapped in a priv block so
> may fail when running under SecurityManager

> I noticed in org.apache.derby.impl.services.bytecode.BCClass.java we have
> this code:
> String systemHome =
> System.getProperty(Property.SYSTEM_HOME_PROPERTY,".");
> writeClassFile(systemHome,false,null);
> which will fail when run under security manager because we have no privilege
> block.
