[JAVA][Liferay] Duplicate key value violates unique constraint for resourcepermissionid in Liferay

Unexpected exception thrown when create new site:

09:47:10,114 ERROR [ajp-bio-8009-exec-113][JDBCExceptionReporter:82] Batch entry 0 insert into ResourcePermission (companyId, name, scope, primKey, roleId, ownerId, actionIds, resourcePermissionId) values ('10157', 'com.liferay.portlet.documentlibrary.model.DLFileEntry', '4', '24728', '10173', '0', '3', '11366') was aborted.  Call getNextException to see the cause.

Solution:

The doubling was caused by the Counter service (not sure what it actually does but assume it generates unique ids for primary keys).

These changes are in the tomcatwebappsROOTWEB-INFclassesportal-ext.properties file

## Counter
##

#
# The counter operates with is own data source to prevent deadlocks. By
# default, the data source created for the counter uses the same settings as
# those used to create the data source used for the rest of the portal. That
# happens by because the counter service will look up the properties
# prefixed with "jdbc.default." to create its data source. See the JDBC
# properties prefixed with "jdbc.default." for more information.
#
# Setting a different value for the counter JDBC prefix allows you to better
# fine tune the counter data source with its own set of configuration
# settings for high availability installations. Note that these settings,
# though separate, are a copy of the default settings with the newly
# overridden values.
#
counter.jdbc.prefix=jdbc.counter.
jdbc.counter.maxPoolSize=3
jdbc.counter.minPoolSize=1
jdbc.counter.numHelperThreads=1

#
# Set the number of increments between database updates to the Counter
# table. Set this value to a higher number for better performance.

counter.increment=100
