Hi i am new to geotools and i am trying to run a simple write example. I
have an existing shape file which has features in it i am attempting to
open and modify. The line FeatureWriter
writer=store.getFeatureWriter(t); appears to set 4 readLocks and when
the t.commit executes i get a stacktrace complaining about : The
following locker still has a lock?
FileDataStore store = FileDataStoreFinder.getDataStore(getFile());
Transaction t = new DefaultTransaction("handle");
FeatureWriter writer=store.getFeatureWriter(t);
Feature feature=writer.next();
feature.getProperty("NAME").setValue("Main St");
writer.write();
t.commit(); // commit operations
writer.close();
t.close();

with temporary copy.

SEVERE: The problem is almost certainly caused by the fact that there
are still locks being held on the shapefiles. Probably a reader or
writer was left unclosed
