Description:
In the file com.mysql.jdbc.DatabaseMetaData there are some cases of a potential NullPointerException:

Line 505:
		} else if (db != null & db.equals(procDb)) {

Line 540:
		} else if (db != null & db.equals(procDb)) {

How to repeat:
Compiler warning.

Suggested fix:
Line 505 should be:
		} else if (db != null && db.equals(procDb)) {

Line 540 should be:
		} else if (db != null && db.equals(procDb)) {

The difference is the double "&" which does a lazy evaluation.
