java.lang.VerifyError: class com... overrides final method getCellRenderer.(II)Ljavax/swing/table/TableCellRenderer ------------------------------------------------------------------------------------------------------------------- Key: JBAS-8514 URL: https://jira.jboss.org/browse/JBAS-8514 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Components: ClassLoading Affects Versions: 6.0.0.M5 Environment: JBoss 6 M5 + Sun JDK 6u16 (but also tried with u21) Reporter: Thomas Fromm Assignee: Scott Stark During the startup of a webapp I get really lots of these errors: 09:02:08,652 WARN [ClassLoaderManager] Unexpected error during load of:com.foo.bar.MyTable: java.lang.VerifyError: class com.foo.bar.MyTable overrides final method getCellRenderer.(II)Ljavax/swing/table/TableCellRenderer; at java.lang.ClassLoader.defineClass1(Native Method) [:1.6.0_16] at java.lang.ClassLoader.defineClass(ClassLoader.java:621) [:1.6.0_16] at org.jboss.classloader.spi.base.BaseClassLoader.access$200(BaseClassLoader.java:52) [jboss-classloader.jar:2.2.0.Alpha8] ... The class MyTable extends from FoobarTable and FoobarTable extends from JTable... I'm little bit confused about the error message, because I've got two getCellRenderer-methods. One of them overrides these one in JTable, the other one is private in both classes (MyTable and FoobarTable). But no one of them is final. Looks like: public class FoobarTable extends JTable { @Override public TableCellRenderer getCellRenderer(int row, int column) { ... } private TableCellRenderer getCellRenderer(Class x){ ... } } public class MyTable extends FoobarTable { @Override public TableCellRenderer getCellRenderer(int row, int column) { ... } private TableCellRenderer getCellRenderer(Class x){ ... } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
