Browser stuck in loop due to not initializing com.liferay.util.Normalizer

My environment is Liferay 6.2, bundled with Tomcat 7, on a Linux machine. My portal was OK but without any development or change in database, I noticed that it isn't accessible. When I try to browse the home page of my site, it is stuck in a loop to refresh the home page and it never stops. Checking details using DevTools shows that the <body/> of the page looks like this:
and a request to browsing /c/portal_layout gets stuck in this loop. Tomcat log shows that the root of problem is
This is the stack trace:

You might want to look after a couple of things:
- Is your installation up to date? (technically it still isn't, even if it was patched, because 6.2 CE is now 4 releases back). This is not the common behavior observed with compromised installations, but I'd still capture this first
- Check your backups. Try if a restored version (on a different server) behaves similarly, or if some defect caused your filesystem to go corrupt with actual missing data. If a restored version behaves differently: Compare the two and see where they differ.
- Check filesystem and memory: Are you running out of resources on the server?

Thank you @Olaf. It seems that what prevents initialization of com.liferay.util.Normalizer is that it has problems with the utility liferay-icu4j.jar. The class Normalizer imports com.liferay.ibm.icu.text.Transliterator and initializing hot deploy thread also throws an exception related to liferay-icu4j.jar. This is the summary of the stack trace:
Let me highlight the root of the problem:

It's the patch level on your JDK. See LPS-118037.
