GCC does not recognize 0b00 as zero

GCC is not recognizing 0b00 as the number 0. This is a snippet from running GCC closure-compiler-v20190819.jar

[java] core_mp.js:210: ERROR - Parse error. missing ) after argument list
[java] this.map.putIfAbsent$TK$TV(t, new Integer(0b00));

This bug was found by a developer in the process of compressing full package files for java2script/SwingJS. https://github.com/BobHanson/java2script. I have reconfigured the java2script transpiler to not output 0b00 format literals. So it is not a priority to me. But still I suggest it get fixed/upgraded, as it is becoming a standard notation in JavaScript.

This was a unique usage case, by the way, in java.util.stream.StreamOpFlags.java.

Apparently the only place in JDK8 where 0b syntax is used!
