@arun-Joseph , thanks. This is exactly where PDB files were located.

To give something back to the community I've prepared a script ([openjfx-build-env.zip](https://github.com/openjdk/jfx/files/6114811/openjfx-build-env.zip)) which installs [Chocolatey ](https://chocolatey.org/) and all required dependencies needed to came up with `JavaFX` & `WebKit` Windows build environment quickly - _please use at your own risk_). 

I suggest using dedicated/clean Windows 10 Virtual machine or Windows Sandbox (​[with 8GB memory](https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-sandbox/windows-sandbox-configure-using-wsb-file#memory-in-mb)).

Steps needed to create JavaFX build from JFX Github repository (with included pull/417):

1. Run `PowerShell` as `Administrator`

2. Run `openjfx-build-env.bat` (extracted from [openjfx-build-env.zip](https://github.com/openjdk/jfx/files/6114811/openjfx-build-env.zip))

3. Run `Cygwin`

4. Run (last two commands won't be needed anymore after this pull request will be merged to the master):
  
   `git clone https://github.com/openjdk/jfx.git` (from `C:`)

   `git fetch https://git.openjdk.java.net/jfx pull/417/head:pull/417`(from `C:/jfx`)

   `git checkout pull/417` (from `C:/jfx`)

5. OPTIONAL: Only if `WebKit` and native debug is needed:
   
   Edit `gradle.properties` (renamed from `gradle.properties.template`) inside `C:/jfx` and set:

   `COMPILE_WEBKIT = true`

   `CONF = DebugNative`

6. Run `chmod +x gradlew` (from `C:/jfx`)

7. Run `./gradlew --console=plain` (from `C:/jfx`)

Side notes:
 - Due to [JDK-8263259](https://bugs.openjdk.java.net/browse/JDK-8263259), the PDB files will be placed inside `c:/jfx/modules/javafx.web/build/win/Debug/bin/jfxwebkit.pdb`.
