Ok, the module is read in cont-sys.rme with \usemodule[jtex]. It 
initializes the lists inside protect / unprotect pair with 
\newtoks\usedAbbreviations and \newtoks\usedReferences along with 
macro definitions.
first of all, here is an alternative to setting your texts; instead of doing the check-next-char stuff yourself ...
%%% handle multilingual texts (and uppercase)
% usage: \setText[lang]{key}{value}
\def\setText{\futurelet\testchar\maybeLangSetText}
\def\maybeLangSetText%
	{\ifx[\testchar \let\next\langSetText
	\else \let\next\defaultSetText \fi \next}
\def\langSetText[#1]#2#3{\def\name{#2@#1}\def\bigname{#2@#1@uppercase}
	\expandafter\def\csname \name \endcsname{#3}
	\expandafter\def\csname \bigname \endcsname{\uppercase{#3}}}
\def\defaultSetText#1#2{\langSetText[\currentmainlanguage]{#1}{#2}}

% usage: \getText{key}
\def\langGetText[#1]#2{\def\name{#2@#1}%
	\expandafter\ifx\csname \name \endcsname\relax
	\name missing!\else\csname \name \endcsname\fi}
\def\getText#1{\def\name{#1@\currentlanguage}%
	\expandafter\ifx\csname \name \endcsname\relax
	\langGetText[\currentmainlanguage]{#1}
	\else\langGetText[\currentlanguage]{#1}\fi}

... you can use the built in functionality: 

\let\dowithText\firstofoneargument

\def\setText
  {\dosingleempty\dosetText}

\def\dosetText[#1]#2#3%
  {\setvalue{\iffirstargument#1\else\currentmainlanguage\fi @TXT@#2}{\dowithText{#3}}}

\def\getText
  {\let\dowithText\firstofoneargument
   \dosingleempty\dogetText}

\def\dogetText[#1]#2%
  {\executeifdefined{\iffirstargument#1\else\currentlanguage\fi @TXT@#2}%
     {\executeifdefined{\iffirstargument#1\else\currentmainlanguage\fi @TXT@#2}%
        {missing #2}}}

\def\getUppercaseText
  {\let\dowithText\WORD
   \dosingleempty\dogetText}

\starttext

\setText{oeps}{whatever}
\setText[de]{oeps}{de-whatever}

\getText{oeps}
\getText[de]{oeps}
\getUppercaseText{oeps}
\getUppercaseText[de]{oeps}

\stoptext

but, when possible, use: 

\setuplabeltext[oeps=whatever]
\setuplabeltext[de][oeps=de-whatever]

{\labeltext{oeps} \mainlanguage[de] \labeltext{oeps} \LABELTEXT{oeps}}

because that is kind of integrated
