Bug #: 52919
Summary: WebappClassLoader.clearReferencesJdbc is not loading
the exact content of the JdbcLeakPrevention.class file
Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: Windows Server 2003
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
org.apache.catalina.loader.WebappClassLoader.clearReferencesJdbc() is
incorrectly reading org/apache/catalina/loader/JdbcLeakPrevention.class file
from disk causing extra bytes in the byte[] passed to
java.lang.ClassLoader.defineClass(String, byte[], int, int, ProtectionDomain).
Having extra bytes at the end of a .class file has always been illegal. This
did NOT cause any issues in the past because in previous JDK releases, the test
for this condition rarely active.
Oracle change their behaviour in java 6 to mark this as an error consequently
any extra bytes leads to errors like these
Caused by: java.lang.ClassFormatError: JVMCFRE118 extra bytes after EOF;
class=com/ibm/ws/runtime/component/JdbcLeakPrevention, offset=2499
