TomCat Servlet execution java.lang.StackOverflowError exception

I am randomly getting the following error on first call to Apache TomCat 8.5.51 after the service restart. The error automatically goes away after sometime which makes it very hard to debug.

What could be the reason for it?

Solution

  • java.lang.StackOverflowError according to the docs

    Thrown when a stack overflow occurs because an application recurses too deeply.

    From the stack trace, the recursion can be seen in lines below. ElemTemplate.execute calls TransformerImpl.executeChildTemplates which in turns calls the former thus establishing the recursion:

    org.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2400)
org.apache.xalan.templates.ElemTemplate.execute(ElemTemplate.java:394).

    Something in the xml estructure or the code parsing it might be causing the java.lang.StackOverflowError.
    Could be worth to check also -Xss jvm setting.
