Description

When using eval and inner method throws exception, this exception gets completely lost and is not found in stack trace.

The problem is in method BuiltinsForStringsMisc.java (eg. https://www.programcreek.com/java-api-examples/index.php?source_dir=freemarker-old-master/src/main/java/freemarker/core/BuiltInsForStringsMisc.java):

           try { 
                return exp.eval(env); 
            } catch (TemplateException e) { 
                throw new _MiscTemplateException(this, env, 
                        "Failed to \"?", key, "\" string with this error:\n\n", 
                        MessageUtil.EMBEDDED_MESSAGE_BEGIN, 
                        new _DelayedGetMessageWithoutStackTop(e), 
                        MessageUtil.EMBEDDED_MESSAGE_END, 
                        "\n\nThe failing expression:"); 
            } 

The caught exception is not logged, nor passed to the new exception.
