As I was working on the issue to upgrade all dependencies to their respective versions, the work progressed smoothly until I had to upgrade Ehcache from version 3.0.0.m4 to version 3.6.3. If you are using Ehcache v3, here is the config doc.
Unfortunately, the developers of Ehcache introduced a non-compatible change, such that it requires a different format of your XML configuration file.
Here is the previous format for activejdbc-ehcache.xml for version 3.0.0.m4:
<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://www.ehcache.org/v3'
xsi:schemaLocation="http://www.ehcache.org/v3 ../../../main/resources/ehcache-core.xsd">
<cache-template name="activejdbc">
<key-type>java.lang.String</key-type>
<value-type>java.lang.Object</value-type>
<heap size="200" unit="entries"/>
</cache-template>
</config>The new format will look like this (3.6.3):
<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://www.ehcache.org/v3'
xsi:schemaLocation="http://www.ehcache.org/v3 ../../../main/resources/ehcache-core.xsd">
<cache-template name="activejdbc">
<key-type>java.lang.String</key-type>
<value-type>java.lang.Object</value-type>
<heap unit="entries">200</heap> <!-- changed format! -->
</cache-template>
</config>If you maintain the older format, your project will break if you upgrade to version of JavaLite 2.3 of 2.3-SNAPSHOT.
So, this article is to help you with this upgrade. If you have any questions, feel free to leave a comment below.
