Erik Bengtson commented on JDO-176:

"*First" is invalid as regular expression.

Exception in thread "main" java.util.regex.PatternSyntaxException: Dangling meta character

> JPOX fails when a query calls String.matches. This bug may be reproduced applying patch
JDO-159. The SQL generation of the following query is incorrect:
> SELECT FROM org.apache.jdo.tck.pc.company.Person WHERE firstname.matches('*First') 
> The LIKE clause of the generated SQL statement contains '*First'. This is a bug. It should
contain '%First'.
