Description of problem:

I used the following negative expressions to filter applications on the 'Discover applications' wizard and they failed .
List of CF applications by space :
space 1 = ['hello-spring-cloud', 'java-backend' , 'book-server']

1) [!h]* - should match apps not starting with 'h'
Actual results : hello-spring-cloud
2) [!a-z]*- Should match apps not starting with a lowercase letter
Actual results : 'hello-spring-cloud', 'java-backend' , 'bookserver'
