JEMH supports comma delimited regular expressions for multiple matching, with this being the case, it can be a problem when your regular expression contains a comma character
Solution

Use the hex code for a comma instead:
^\x2c
To be able escape \E at the end, you can use more back slashes as per following example:
^{Message=(.*)\\\\E}
