This weakness takes an input of "<qsize> <string>" where qsize is the length of the array to generate and sort for timing and string is an arbitrary string to use as data to pass around. The weakness uses a double checked lock to initialize a shared static data class in an attempt to be efficient (not block threads when the data is initialized) however this introduces a possibility for a thread to return from the method while another thread is in the process of initializing the data. This will lead to an access of uninitialized data, resulting in a StringIndexOutOfBoundsException. This malicious behavior is tiggered when qsize >= 5000000, and not to occur when qsize <= 50. stonesoup.jtree.Main $SS_TC_ROOT/$SS_TC_INSTALL:$SS_TC_ROOT/$SS_TC_INSTALL/lib/*:$SS_TC_ROOT/$SS_TC_INSTALL/lib/opt/*:$SS_TC_DEPS/java/stonesoup/lttng/lttng-stonesoup-0.1.jar UNSPECIFIED UNSPECIFIED java $SS_JAVA_OPTS -Djava.library.path=$SS_TC_DEPS/lib64/ -cp "$SS_JAVA_CLASSPATH" stonesoup.jtree.Main env ANT_HOME=$SS_TC_DEPS/ant ant $SS_ANT_OPTS -Dstonesoup.database.postgres.required=no -Dstonesoup.hibernate.postgres.required=no -Dstonesoup.hibernate.mysql.required=no -Dstonesoup.database.mysql.required=no -Dstonesoup.socket.required=no -lib $SS_TC_DEPS/java/stonesoup/lttng/lttng-stonesoup-0.1.jar -Dstonesoup.socket.lib.dir="$SS_TC_DEPS/java/stonesoup/socket" -Dstonesoup.hibernate.mysql.lib.dir="$SS_TC_DEPS/java/stonesoup/hibernate/mysql" -Dstonesoup.hibernate.postgres.lib.dir="$SS_TC_DEPS/java/stonesoup/hibernate/postgres" -Dstonesoup.database.mysql.lib.dir="$SS_TC_DEPS/java/stonesoup/database/mysql" -Dstonesoup.database.postgres.lib.dir="$SS_TC_DEPS/java/stonesoup/database/postgres" -Dstonesoup.lttng.lib.dir="$SS_TC_DEPS/java/stonesoup/lttng" -Dstonesoup.lttng.dummy.lib.dir="$SS_TC_DEPS/java/stonesoup/lttng-dummy" -Ddir.dist=$SS_TC_ROOT/$SS_TC_INSTALL build cp -r lib $SS_TC_ROOT/$SS_TC_INSTALL Environment variable defining string value.
