java.lang.NoSuchMethodError when running on Java 8

[osobolev]

Error in version 1.3.0. Stacktrace:

java.lang.NoSuchMethodError: java.nio.CharBuffer.limit(I)Ljava/nio/CharBuffer;
	at org.owasp.encoder.Encode$Buffer.encode(Encode.java:1325)
	at org.owasp.encoder.Encode.encode(Encode.java:1237)
	at org.owasp.encoder.Encode.forXml(Encode.java:756)
	at org.owasp.encoder.Encode.forHtml(Encode.java:145)

Error line looks like
_input.limit(remaining).position(0);

where _input is CharBuffer. Method limit(int) differs in Java 8 and Java 9: in Java 8 it is final in the base class Buffer, and in Java 9 it is overriden in CharBuffer with covariant return type.

Seems that it is compiled against Java >= 9, so that limit(int) is linked to CharBuffer.limit(int) which is missing in Java 8.

The solution is simple: in the root pom.xml change

                    <execution>
                        <id>compile-java-8</id>
                        <goals>
                            <goal>compile</goal>
                        </goals>
                        <configuration>
                            <source>1.8</source>
                            <target>1.8</target>
                        </configuration>
                    </execution>

to

                    <execution>
                        <id>compile-java-8</id>
                        <goals>
                            <goal>compile</goal>
                        </goals>
                        <configuration>
                            <release>8</release>
                        </configuration>
                    </execution>

Thank you for providing the suggested fix.

Thank you for fixing this 😃 Do you have any plans to release this soon? It unfortunately currently blocks us from updating to 1.3.

I'll be releasing this shortly.
