Tomcat 5.5 was last released 2012-10-09, e.g. 8 years ago, just after its announced end-of-life in September 2012.

Java 11 was released in September 2018, 6 years after Tomcat 5.5 went to unmaintained state.

Any suggestion where the problem can be?

You do the math on release dates above. Upgrade!
