reReplace NullPointer Exception - Lucee-6

dev support
1

I am getting an intermittent NullPointer on reReplace.

fileSep is one of these characters: \ / .

return reReplace(path, “[\/]+”, fileSep, “all”);

I reviewed the Lucee code and it is crashing on

[Lucee/core/src/main/java/lucee/runtime/functions/string/REReplace.java at 6.2 · lucee/Lucee · GitHub](https://RERelace.java on line 48)

I noticed the code on line 48 is different then the line 43.

I reviewed the code on:

  • reFind
  • reFindNoCase
  • reMatch
  • reMatchNoCase
  • reReplace
  • reReplaceNoCase

reReplace and reReplaceNoCase are coded different then the rest when it comes to use of pc ( page context )

Regex regex = ((PageContextImpl) ThreadLocalPageContext.get()).getRegex();

vs

Regex regex = ((PageContextImpl) pc).getRegex();

@micstriit @Igal - My knowledge of Java is limited though I have written a few things in Java over the years. This issue listed above is related to how ThreadLocalPageContext.get() works. I submitted a pull request for reReplace and reReplaceNoCase which I am sure needs help.

This did solve my reReplace issue but I then ran into another ThreadLocalPageContext.get() null pointer issue.
