Hello,

I was trying to do search and replace in jmeter (3.2 r1790748) for a change
in URL for my application. I did as shown in the snaps below but found that
the search replace was stuck and did not responded even after about 30 mins.

I did a bit of digging using jvisual vm and found that the method
"org.apache.jorphan.util.JOrphanUtils.replaceAllWithRegex()" had the highest
self time and it kept increasing with time (obviously!).

Seems to be a bug. Can i please get some suggestions?
I just filed a bug https://bz.apache.org/bugzilla/show_bug.cgi?id=61054

The problem is, that you are replacing a string with a string, that includes the search. That leads to an endless loop in JOrphanUtils#replaceAllWithRegex.

A simple testcase would be to add a ThreadGroup containing a HTTP Sampler with a Parameter having a key "name" and a value "abc".

Now, if one does a find replace with "abc" as the search and "abcabc" as the replacement, "replace all" will never come to a halt :(

Regards,
 Felix
