java.lang.NoSuchMethodError: org.springframework.http.MediaType.getCharset()Ljava/nio/charset/Charset
Unbelievable...foiled by class loading issues once again...an uber jar named activemq-minimal-5.13.3.jar
had references to spring
jars in it that was causing the conflict. activemq-minimal-5.13.3.jar
comes before spring
alphabetically so the classes in that activemq
jar were being loaded/used over the spring
jars. Updated my ant build to load the spring
classes first and now I'm all set.
The way I found out is I put all of my 3rd party libs together in a "Test" project and added/deleted jars (with somewhat of an inclination where the problem was) until I was able to pinpoint where the class loading issue was.
org.springframework.http.MediaType.getCharset()
was introduced since 4.3 if java did not find it that mean that you have a spring-core version below 4.3.1 in your classpath which get loaded and used.
In spring latest version they have modified
org.springframework.http;
MediaType contentType = headers.getContentType();
Old :
contentType.getCharSet()
New :
contentType.getCharset()
