ProcessBuilder memory leak and memoy lock issues

[SivaBalaSubramanian-Vetrivel]

Hi All

The code below uses PowerBuilder to execute  power shell. Just want to confirm the chances of memory leak and memory lock.
As per this link https://bugs.openjdk.java.net/browse/JDK-8054841 memory leak got fixed, however do we have any details on memory lock.
I would appreciate if some one share  any workaround, fix

if (OSDetector.isWindows()) {
pb = new ProcessBuilder("cmd.exe", "/c", "chcp", codePage, ">", "NUL", "&", powerShellExecutablePath,
"-ExecutionPolicy", "Bypass", "-NoExit", "-NoProfile", "-Command", "-");
} else {
pb = new ProcessBuilder(powerShellExecutablePath, "-nologo", "-noexit", "-Command", "-");
}
