javac and java are from the same distrib (javac does not print detailed version info, that is why I''m mentioning java version), so it is javac 1.5.0_b64
so I compile with JDK 1.5.0_b64, run on Harmony and it fails Thanks, Mikhail 2006/6/7, Jimmy, Jing Lv <[EMAIL PROTECTED]>:

What's more, shall we also suggest that everyone use a latest version of javac to avoid such problem? > >> >> Regards, >> Tim >> >> Mikhail Loenko wrote: >> > Are you compiling with "jsr14" as our build does? >> > >> > I'm using BEA javac with "jsr14" it compiles to something like this: >> > for(i=0; i < values.length; i++ ) >> > if( values[i].name().equals(argument) ) >> > return values[i].name().equals(argument) >> > throw IAE >> > >> > 2006/6/7, Tim Ellison <[EMAIL PROTECTED]>: >> >> Maybe compiler specific. >> >> >> >> Looking at Proxy.Type it appears that the Sun compiler 1.5.0_06 >> >> delegates to the Enum type: >> >> >> >> public static Type valueOf(String name) >> >> { >> >> return (Type)Enum.valueOf( >> >> Proxy.class$java$net$Proxy$Type != null ? >> >> Proxy.class$java$net$Proxy$Type : >> >> ( >> >> Proxy.class$java$net$Proxy$Type = >> >> Proxy._mthclass$("java.net.Proxy$Type") >> >> ), >> >> name); >> >> } >> >> >> >> >> >> and the Eclipse compiler 3.2RC4 looks up the constant itself: >> >> >> >> public static Type valueOf(String s) >> >> { >> >> Type atype[]; >> >> Type type1; >> >> for(int i = (atype = ENUM$VALUES).length; --i >= 0;) >> >> if(s.equals((type1 = atype[i]).name())) >> >> return type1; >> >> throw new IllegalArgumentException(s); >> >> } >> >> >> >> >> >> In the Sun compiler a null name argument gets passed to >> >> Enum#valueOf(Class, String) where I check and throw NPE. >> >> >> >> In the Eclipse compiler the line if(s.equals(...)... will cause a NPE >> >> iff there are entries in the VALUES array (otherwise it doesn't go >> into >> >> the for-loop) and throws an IAE without going into my code. >> >> >> >> Maybe I can withdraw the null name test while we settle this? >> > >> > We now have 3 tests failing >> > >> > Thanks, >> > Mikhail >> > >> > >> > >> >> >> >> Regards, >> >> Tim >> >> >> >> >> >> Andrew Zhang wrote: >> >> > Hi, Stepan, >> >> > >> >> > The test you metioned is passed in my environment: >> >> > RI version: 1.5.0_02. >> >> > Linux: Read hat Enterprise Linux AS(2.4.21-15.EL) >> >> > >> >> > Is the problem caused by earlier version javac? >> >> > >> >> > I remember that RI of earlier verion throws IAE instead of NPE >> when the >> >> > arguement is null. >> >> > >> >> > Would you please check "java" version? >> >> > >> >> > Thanks. >> >> > >> >> > >> >> > >> >> > >> >> > >> >> > On 6/7/06, Stepan Mishura <[EMAIL PROTECTED]> wrote: >> >> >> >> >> >> I found the reason - tests expect NPE when valueOf(null) is invoked >> >> but >> >> >> IAE >> >> >> is thrown instead.
