The `BufferedReader` in `PreparedCommentHeader#update()` is initialized with a read-ahead limit of 2048 bytes. If a file is larger than that, the mark will be invalidated while the `update()` method skips through the file line-by-line and when no valid existing license header was detected, the `BufferedReader#reset()` method will fail. ```text java.io.IOException: Mark invalid at java.base/java.io.BufferedReader.reset(BufferedReader.java:517) at java_io_BufferedReader$reset$1.call(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:47) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:115) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:119) at org.cadixdev.gradle.licenser.header.PreparedCommentHeader$_update_closure2.doCall(PreparedCommentHeader.groovy:84) ```
