Re: Strippable check system in GWT 2.8?

Thank you Thomas, <set-property name="jre.checks.checkLevel" value="MINIMAL" /> in my gwt.xml file works :-)

The javadoc and first few lines of the class tells it all (note that System.getProperty is the emulated one here, so the properties are from your gwt.xml files, not the JVM System properties when calling the GWT compiler)

FWIW, the properties (and their default value) are defined in https://github.com/gwtproject/gwt/blob/2.8.0/user/super/com/google/gwt/emul/Preconditions.gwt.xml

hi,

I heard that the GWT 2.8 check system is strippable (source: https://www.youtube.com/watch?v=P4VhPck5s_g&t=1337s).

By defaut the check level would be normal, which means that the generated js code will do all checks (such as collections bounds checks, API usage checks, java type checks, ...). But if we are confident that the application successfully passes all checks, it seems possible to reduce that check level from normal to optimized or minimal and get a smaller and faster compiled production code.

I haven't found any documentation about this feature, not sure it is actually documented.

Does anybody know how to tell the GWT compiler to change that check level?
