执行.bat文件的时候报since it reqires a 1.6 compliant jvm 是什么原因

执行.bat文件的时候报since it reqires a 1.6 compliant jvm 是什么原因

在上一次查看tomcat启动文件都干点啥一文中，我们总结出，startup.bat文件的作用就是找到catalina.bat文件，然后把参数传递给它，在startup.bat中，调用catalina.bat的命令call "%EXECUTABLE%" start %CMD_LINE_ARGS%，其中"%EXECUTABLE%"这个就是catalina.bat文件，这个命令至少向catalina.bat传递一个参数--start.
接下来看一下catalina.bat中的内容，内容很长：

在第1行，和第17行中的内容已经在前一章中做出说明，在此处不再敖述，我对于18-85行的这段注释比较感兴趣：

1 rem ---------------------------------------------------------------------------
2 rem Start/Stop Script for the CATALINA Server
3 rem
4 rem Environment Variable Prerequisites
5 rem
6 rem CATALINA_HOME May point at your Catalina "build" directory.
7 rem
8 rem CATALINA_BASE (Optional) Base directory for resolving dynamic portions
9 rem of a Catalina installation. If not present, resolves to
10 rem the same directory that CATALINA_HOME points to.
11 rem
12 rem CATALINA_OPTS (Optional) Java runtime options used when the "start",
13 rem or "run" command is executed.
14 rem
15 rem CATALINA_TMPDIR (Optional) Directory path location of temporary directory
16 rem the JVM should use (java.io.tmpdir). Defaults to
17 rem %CATALINA_BASE%\temp.
18 rem
19 rem JAVA_HOME Must point at your Java Development Kit installation.
20 rem Required to run the with the "debug" argument.
21 rem
22 rem JRE_HOME Must point at your Java Runtime installation.
23 rem Defaults to JAVA_HOME if empty.
24 rem
25 rem JAVA_OPTS (Optional) Java runtime options used when the "start",
26 rem "stop", or "run" command is executed.
27 rem
28 rem JAVA_ENDORSED_DIRS (Optional) Lists of of semi-colon separated directories
29 rem containing some jars in order to allow replacement of APIs
30 rem created outside of the JCP (i.e. DOM and SAX from W3C).
31 rem It can also be used to update the XML parser implementation.
32 rem Defaults to $CATALINA_HOME/endorsed.
33 rem
34 rem JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start"
35 rem command is executed. The default is "dt_socket".
36 rem
37 rem JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start"
38 rem command is executed. The default is 8000.
39 rem
40 rem JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start"
41 rem command is executed. Specifies whether JVM should suspend
42 rem execution immediately after startup. Default is "n".
43 rem
44 rem JPDA_OPTS (Optional) Java runtime options used when the "jpda start"
45 rem command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
46 rem and JPDA_SUSPEND are ignored. Thus, all required jpda
47 rem options MUST be specified. The default is:
48 rem
49 rem -agentlib:jdwp=transport=%JPDA_TRANSPORT%,
50 rem address=%JPDA_ADDRESS%,server=y,suspend=%JPDA_SUSPEND%
51 rem
52 rem LOGGING_CONFIG (Optional) Override Tomcat's logging config file
53 rem Example (all one line)
54 rem set LOGGING_CONFIG="-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties"
55 rem
56 rem LOGGING_MANAGER (Optional) Override Tomcat's logging manager
57 rem Example (all one line)
