If I instantiate template Java Beans | Customizer, generated code is not always the same. Sometimes is generated: private void initComponents() { setLayout(new java.awt.BorderLayout()); } But sometimes is generated: private void initComponents() { setLayout(new java.awt.BorderLayout()); } Yes, the only difference is in white space, but it can cause problems in automated tests.
I am sorry I am not able to reproduce this problem. If it is still an issue, please, include the offending test.
