Advanced search for java code [closed]

Question

Is there any easy way to get advanced search in Java code? I'm migrating our application from Glassfish 2 to Glassfish 4. Few libraries changed their way of handling inputs and I would like find where this specific situations will occur.

For example: JPA 1.2

MyEntity some = entityManager.find(MyEntity.class, 1234);
some.setIdMyEntity(null);
entityManager.persist(some);

Code similar to this above was working in a way it persisted new entity with new auto generated id (if appropriate annotation was in entity).

JPA 2.2 The same code will produce error

The attribute [idMyEntity] of class [my.package.MyEntity] is mapped to a primary key column in the database. Updates are not allowed.

I understand reasons behind this change and I would like to fix my application and find places which need fix as precisely as it is possible.

To find these I used regular expression \.setId[a-zA-Z]+\(null\); However there are hundreds or even thousands of matches and 90% are false positives. That's why I would search engine which could do something like that:

Look for invocation of setter (which is related to field annotated as @Id) 
with argument null on object which is instance of class annotated as @Entity

As I told this is only example so basically what I'm looking for are ways of advanced searching in Java code. Anything more than dead simple search/ regular expression search/ find usages capabilities are welcome.
