In jpackage test suite there is a test utility WindowsHelper.queryRegistryValue
. It is used to verify changes to Windows registry that can be done by
installer packages. It spawns `reg.exe query` process and parses its output.
This patch adds support for quering empty values and additional REG_* datatypes.
Correctness was verified manually with the following registry values:
// (Default) REG_SZ test1
// string_val REG_SZ test2
// string_val_empty REG_SZ
// bin_val REG_BINARY 4242
// bin_val_empty REG_BINARY
// dword_val REG_DWORD 0x2a
// qword_val REG_QWORD 0x2a
// multi_string_val REG_MULTI_SZ test3\0test4
// multi_string_val_empty REG_MULTI_SZ
// expand_string_val REG_EXPAND_SZ test5
// expand_string_val_empty REG_EXPAND_SZ
