yes, i think so, it is ecj that did the compilation not the jre/jdk...
max version u can go with tomcat6 is java8, see
} else if(opt.equals("1.7")) {
settings.put(CompilerOptions.OPTION_Source,
CompilerOptions.VERSION_1_7);
} else if(opt.equals("1.8")) {
settings.put(CompilerOptions.OPTION_Source,
"1.8"); // CompilerOptions.VERSION_1_8
} else {
log.warn("Unknown source VM " + opt + " ignored.");
settings.put(CompilerOptions.OPTION_Source,
CompilerOptions.VERSION_1_5);
}
i suggest you really consider upgrade tomcat.
my path was tomcat6 - > tomcat8 -> tomcat10
